With every other popular case manufacturer we can think of sporting some sort of mini-ITX offering, we’ve been wondering for a while why Corsair hasn’t added the dinky form factor to its extensive list of cases. Its flagship Obsidian 900D case made us even more curious seeing as it filled the only other slot that Corsair had to fill — a super high-end water cooling case — and that was nearly a year ago.

So it’s fair to say Corsair is somewhat late to the party with its offering, the Corsair 250D. And this poses somewhat of a dilemma; how to create something that can compete with the likes of the BitFenix Prodigy and Phenom, EVGA Hadron Air and Cooler Master Elite 130 Advanced?

The solution is quite simple. Listen to what people liked and didn’t like about those cases and pile all this information in to your design. Of course, that’s easier said than done. We’re talking about the proposed case offering good water-cooling support along with good air cooling like the Prodigy, while being small and compact like the Hadron Air, while sporting good looks like the Phenom but finding a balance between size, ease of use and support for high-end hardware like the Elite 130 Advanced. Not a tall order then.

So, today we’re looking at what Corsair has come up with. We honestly weren’t sure which of Corsair’s numerous case lines it would fall under — the edgy Graphite series or the premium Obsidian series — but Corsair has chosen its high-end line to debut its first mini-ITX case, giving us the Corsair Obsidian 250D. This follows on nicely, of course, from the micro-ATX Corsair Obsidian 350D but the latter’s new smaller sibling looks far less bland and far more interesting, especially with a price tag of just £72.

Size-wise, if the Prodigy was too big for you, then the 250D’s smaller height and depth will be right up your street (the 250D is over 11cm shorter and a shallower too). It is a wide case though — at 28cm it’s a good 3cm wider than the Prodigy. However, that’s to be expected given that this is more of a cube case than a tower like the Prodigy and Hadron Air.

However, it’s by far the biggest mini-ITX cube-style case we’ve reviewed and the interior, which we’ll look into over the page, is very different to other cases we’ve looked at too. the exterior, though, feels very well made, and the roof and both side panels are standard slide-in affairs and are made of individual steel panels. One of these sports a huge vent over the GPU area, while it’s opposite number does the same for the 250D’s side fan mounts. Thankfully, the roof section does include a window and to be honest, Corsair has absolutely done the right thing here and provided a small but adequate view of the interior but focused more on cooling.

In fact, while the case is certainly elegant and well thought-out in several ways, cooling does appear to the main focus. The front panel sports an external 5.25in bay — still useful for fan controllers and bay reservoirs even if not for an optical drive — but beneath it sits a huge (considering the small size of the 250D) pop-down panel that reveals an equally gargantuan removable fan filter and accompanying 140mm fan (it can also fit up to 200mm fans). It’s an interesting design that has the potential to offer a good balance of cooling and low noise, as the front panel sits a good 20mm away from the recessed front of the case, meaning air can be drawn in through substantial gaps round the edge.

The front section also plays host to the usual two USB 3.0 ports and 3.5mm headphone and microphone jacks, while the power button actually sits to the top left of the 5.25in bay. Beneath this sits a tiny reset button that looks pretty immune to accidental presses. The underside doesn’t offer too many exiting features except for rubber feet and a PSU dust filter, while the rear gives you some idea of the unique layout Corsair has chosen.

The full-size PSU mount is located at the rear beneath the motherboard, not unlike the arrangement in the Prodigy, while to its left sits a bunch of storage mounts. The motherboard sits horizontally — again like the Prodigy, with two PCI expansion slots and two rear 80mm fan mounts, neither of which are occupied out of the box.

Corsair Obsidian 250D « 7Review

A great pint-sized mix of low noise, great cooling and sensible design
This year looks set to be a great year for mini-ITX fans and Corsair has, at last, finally got on the bandwagon too. Rumblings of a Corsair case mini-ITX have been felt for some time, but the Obsidian 250D has finally hit the shelves. It’s Corsair’s smallest ever case and, thankfully, one of its cheapest too. The Obsidian 250D is certainly looking to usurp the likes of BitFenix’s Prodigy and Antec’s ISK600.
The exterior exudes the typical clean, styling of Corsair’s other Obsidian cases, with its all-black finish laced with brushed metal, and a minimum of ports and switches on display. Cooling was clearly at the forefront of the minds of Corsair’s design team, with a large vent in either side panel, while on the base the PSU has its own removable dust filter.

Meanwhile, the front of the case sports a large pop-down door, which makes up most of the front section, and behind it lays another removable fan filter, which covers the large air intake.
While Corsair is clearly committed to giving the 250D a clean, minimalist look, it’s also added a top window to the case, which gives a great view of the motherboard area to show off your shiny hardware. The use of individual side and top panels contrasts directly with the Antec ISK600’s neat-looking, one-piece shell, but the panels are easier to fit, and they also mean you don’t have to remove the whole shell to get at just one section of the interior.
The Obsidian 250D is very compact too, measuring just 290mm high and 351mm deep. The Prodigy, by comparison, shaves a few centimetres off the width, but is over 11cm taller.
Despite the small size of mini-ITX cases, there’s a surprising amount of variation when it comes to their layout, and the Obsidian 250D is no exception. Like the Prodigy, it sports a large front intake area, with support for 120,140 and 200mm fans, and a 140mm AF140L fan included.
Meanwhile, the left panel is equipped with a magnetic dust filter, and the right side panel has two 120mm fan mounts, with a 120mm fan included, and there are two additional 80mm fan mounts at the rear too. For water- cooling fans, you can squeeze Corsair’s h200i dual 120mm-fan all-in-one liquid cooler inside the chassis, or a half-height radiator of your choice, while the front fan mount could play host to a full-height single 120 or 140mm-fan radiator. There’s even room for a 180mm-fan radiator here too, although it’s a bit of a squeeze. Not only that, but the large area between the front fan and motherboard tray is perfect for mounting a combined pump and reservoir too.
Considering the side of the case, the amount of room for water-cooling equipment is remarkable.
The Obsidian 250D won’t leave too many people wanting for storage space either; a large drive cage next to the PSU mount in the base offers two dedicated 2. 5in SSD tool-free bays, along with an additional two 3.5in or 2.5in bays as well, which are again tool-free.
These are all accessed by removing a small vent at the rear of the case, which is held in by thumbscrews. This access process is a little long-winded, but you won’t have to do it regularly, and there’s no need to remove the side panels either. Corsair has also seen fit to include a full-sized 5.25in bay – a feature the Antec ISK600 lacked, although installing an optical drive will restrict CPU cooler height to just 95mm. If you don’t need the bay then the mount is removable and you’ll gain another 40mm of clearance.
There’s also room for 300mm graphics dual-slot cards, which is enough space for all but monstrous dual-GPU models such as Radeon HD 7790 6GB cards, and those with large third-party coolers. Meanwhile, the PSU mount sits under the motherboard, and PSU length is essentially unlimited; there’s even room for the cables on modular PSUs, which the Prodigy can have trouble accommodating.
The only slight downers in terms of design are that the insides get a little cramped in comparison to the Prodigy, and there isn’t a lot of room for cable routing, due to the small size of the case. However, there are a few handy cable-tie mounts in front of the PSU and drive cage, so you can at least build a vaguely tidy system.
Performance With its unique cooling arrangement, we initially couldn’t predict how the Obsidian 250D would perform, but we weren’t disappointed. Its CPU delta T of 52°C was 9°C warmer than that of the larger Prodigy, but also 4°C cooler than the ISK600. It was its GPU delta T that really wowed us though – at 47°C, it’s the equal top-performing mini-ITX case, matching Fractal Design’s Node 304 on its highest fan speed setting and bettering the ISK600 again by 4°C.
This is likely due to the fact that the graphics card’s fan is placed right against the side panel, meaning it has direct access to cool outside air. While the Prodigy’s CPU delta T was much lower – this is due to its noisier, high-airflow fans – the Obsidian 250D, by comparison, was extremely quiet.
Conclusion With the Obsidian 250D, Corsair has created a fantastic first effort at a mini-ITX case. It has many of the best features of the competition, plus plenty of unique features of its own.
The ability to house two radiators, including Corsair’s large h200i, is amazing in a case this size, yet it manages to offer good water-cooling support without sacrificing air cooling.
The interior can be a little cramped, and there’s little space to hide cables, but that’s the same for any case of this size.
While CPU cooling isn’t spectacular, to Corsair’s credit, it could easily be improved by using an all-in-one liquid cooler as opposed to our test cooler. The all-round good specifications, excellent GPU cooling, small size, low noise, great water-cooling support and very reasonable price tag make the Obsidian 250D our new favourite mini-ITX case.

Case Corsair Obsidian 250D

Last fall, we received a review case Corsair Obsidian 350D, which at that time was the smallest and most affordable representative of the line. But after just a few months, Corsair decided to expand the popular lineup and add an even more compact model with the 250D index to it.

This case does not differ much in weight and volume from the 350D model, but it is much smaller in height and wider in width. That is, from a completely traditional tower, a hull aspiring to the shape of a cube turned out. This solution allowed engineers to place a Mini-ITX motherboard, a full-sized power supply, up to four drives and a full-sized gaming graphics card in a relatively compact size.

The case box is made of plain nondescript cardboard and has product schematics printed on the outside, along with product features and brief technical specifications. There are slots for easy portability. The case inside the box is securely fixed, nothing threatens its safety.

In addition to the case itself and elements of the cooling system, the package includes instructions in all major languages, including Russian, as well as a small cardboard box with a set of screws and four disposable ties.

Corsair Obsidian 250D has only one color and design option — black, with a Plexiglas plate at the back of the top panel. The chassis of the case is made of steel, the basis of the front panel and all its elements is plastic, but on the outside, the “facade” of the case is covered, albeit thin, but still aluminum plates — it turned out, on the one hand, beautifully, and on the other hand, relatively budget.

The design of the case fits perfectly into the Obsidian line. Here, exactly according to the same principle, the design of the front panel with a slotted frame along the edges is made, the same power button and indicators are used, steel and aluminum are painted according to the same principle. In general, the body looks quite strict, solid and to some extent minimalistic.

The most difficult and painful issue for the Corsair Obsidian 250D is its proportions and dimensions. The case is too low and handsome to fit under a desk, but too wide and square to sit neatly on a desk next to a monitor. It is also not so easy to attach such a cube to the living room — unless you try to put it symmetrically to the subwoofer of the audio system or place the case instead of it.


The chassis is a one-box design with the power supply located underneath. The design provides for the installation of full-size ATX PSUs, including those with increased depth.

The lower part of the volume is occupied by a niche for the power supply and a basket for four drives with a quick-release sled. The motherboard tray sits directly above these two elements, while the top of the case only has a removable cage for a single 5.25″ optical drive.

Thanks to this arrangement, the Obsidian 250D can accommodate a CPU cooler up to 140mm high and a dual-slot video card up to 305mm long, which means that almost all models on the market will fit.


Dimensions Corsair Obsidian 250D — 351 (L) × 277 (W) × 290 (H) mm. Chassis weight without power supply — 4.42 kg. The thickness of the steel used is 0.7 mm, which is quite enough to maintain the good strength of the compact body, even with the presence of a large number of perforated holes.

The main frame of the front panel is made of black plastic, painted, judging by the visual signs, in bulk. The high front legs are also part of this frame and feature the typical Obsidian trapezoid shape. The main part of the front panel is occupied by a plastic plate, on which a thin aluminum plate is glued. Under this plate are a dust filter and a front case fan, to remove it, just press on the two spring-loaded latches and pull the plate towards you.

The top of the front panel has a power and reset button, activity indicators, two USB 3.0 ports, and a standard set of microphone and headphone jacks. Buttons and ports are spaced at different edges of the panel, the central part is occupied by a blank five-inch bay. Thin aluminum plates are also glued on all elements of the front panel to give the case a more concise and uniform look.

The power button has the shape of an impressive rectangle. Power and HDD activity indicators are built into its left and right edges, respectively. While pressing, you may get the false impression that the button mechanism is broken and works intermittently, but in fact this is not the case — all presses are processed absolutely stably, it’s just that the button travel is relatively small, and during pressing it can fall on one of the sides.

Both indicators are made in white, they do not glow too brightly, the eyes should not get tired of them. The Reset button is located a little lower, it has the shape of a circle and it is almost impossible to press it with your finger without using thin tools at hand.

USB 3.0 ports are only one centimeter apart, so connecting two large devices at the same time can be a problem.

The side walls of the housing are identical. Their upper part is heavily perforated to help the case fans and the graphics card cooling system. It is worth noting that in this case, unlike most other Mini-ITX cases of similar dimensions, both side and top walls are removed separately, and do not represent a single U-shaped casing.

There is no perforation on the top wall, but there is an impressive Plexiglas window. Use it, according to the official manual, you need to «visual inspection of high-performance components.» Well, why not. The main thing is that dust does not get inside through the plexiglass.

The back of the Obsidian 250D looks more saturated than most other cases. The fact is that access to the compartments with the power supply and drives is carried out not from the inside of the case, but from the outside — just from the back wall.

There is practically nothing interesting on the bottom wall. At the end of all plastic legs, small soft rubber inserts are glued for quieter PC operation on a hard surface. It is also clearly seen here that the lower part of the chassis base is not made even, but with an extruded pattern, designed to slightly increase the rigidity of the structure.

Cooling System

For a Mini-ITX Chassis, the Corsair Obsidian 250D has a truly outstanding cooling system with 5 case fans, 2 of which are included in the box.

The main intake fan is mounted on the front wall of the chassis. It has a size of 140 mm, but if desired, it can be replaced both with a more compact 120 mm counterpart, and with a 200 mm giant. A fine synthetic mesh dust filter is installed in front of the fan. To remove it, it is enough to remove the plastic-aluminum plate and press on the two latches.

Please note that the slot around the perimeter of the front panel is not only an unusual design element, but also a smart way to get cool air to the front fan, avoiding the use of ugly meshes and grilles.

The second complete fan is installed on the right wall of the chassis, it has a size of 120 mm. Next to it, you can install another fan of the same size. In the case of using a liquid cooling system, a 240-mm radiator is attached to this place, but in this case, conventional fans will have to be abandoned — everything will simply not fit into the case together.

The fan on the side wall is also blown by default. To protect against dust, dust filters made of the same fine synthetic mesh are installed on both side walls. The method of attaching filters is already familiar from other representatives of the Obsidian line — this is a magnetic frame along the edge of the filter. The solution is simple, but at the same time very convenient: you don’t need to unscrew, bend or peel off anything, the filter is removed in a second and put back just as quickly.

Two more 80mm fan slots are located at the top of the back of the case. Their use may make sense if a passive cooler with a massive heatsink up to the very top wall is chosen to cool the CPU/APU.

The fourth dust filter is located on the bottom wall in the area of ​​the power supply fan cutout. It is made of a similar material and is also easy to remove: just slightly press on the latch at the bottom of the rear panel and the frame with the filter will obediently slide out along the guides.

In general, the case cooling system can be considered very successful, thoughtful and easy to use. The fan power should be enough for even the hottest components, while the absence of extra holes and quick-release dust filters will help keep the inside clean and tidy.

Assembling the system unit

It should be noted right away that to assemble an average PC in this case, you practically do not need a screwdriver: the Obsidian 250D uses knurled screws and screwless component mounting systems everywhere.

The top and both side panels are fixed with two knurled screws. The method of fastening the walls is reclining-sliding. The mechanism always works clearly and without complaints, it is not required to put the case on its side to install the side wall in place.

The rear I/O blank is traditionally omitted, and four Mini-ITX motherboard stands are pre-mounted on the base. You will have to fix the board with ordinary screws, and this is the only place where you cannot do without a screwdriver.

To install the power supply and drives, remove two steel plates from the bottom of the rear panel, each held on by four thumb screws. After that, it will be possible to remove the sled for 2.5″ and 3.5″ drives, a pair of each type, that is, 4 pieces in total.

Full-size hard drives are secured to the carrier with metal pins, two of which are inserted immediately and two are pulled tightly onto the drive. After installation back into the basket, the fixation turns out to be quite reliable, although there is still play in the vertical plane. Unfortunately, there is no possibility to further strengthen the fasteners with screws.

For 2.5″ sleds, the attachment mechanism is completely the same, the play after installation in the basket is also present, perhaps even stronger. If necessary, the 3.5″ sled can be used to install notebook format drives, for this the drive will need to be screwed to the plastic bottom of the sled with four screws. Thus, four 2.5″ drives or two 2.5″ and two 3.5″ drives can be installed in the case at the same time.

The power supply simply slides into the case with the wires inside through the appropriate hole in the rear wall. It is most logical to place it with the fan down, but the design of the case also allows you to turn it 180 degrees, although this does not make much sense. After installing the power supply, the fixing plate is installed in place, and the PSU is screwed to it with the same thumbscrews.

The optical drive mount is also screwless. It is enough to squeeze out the plug, open one plastic latch with metal pins, roll the drive along the guides and close the latch. Unfortunately, in practice, the latch often fails, falls out of its spacers, and does not fix the drive securely enough. Unfortunately, there is no possibility to strengthen fasteners with screws either. Fortunately, the relevance of optical drives is steadily declining, so most potential case buyers will not run into problems.

Expansion boards are fastened with screws, each of the two slots is covered with its own removable cover. Screws, as elsewhere, with knurled head. Additionally, a steel L-shaped plate is called upon to improve fixation, which is the same for two slots. It cannot be completely removed to the side — only raised a few centimeters along the guides, which is not always convenient and can interfere with the installation of a video card. But to lose this record will not work.

All case fans are mounted with conventional Phillips screws, small rubber dampers are only on the seats for rear coolers size 80mm. Fans are connected with a standard 3-pin connector, there are no adapters for connecting to a power supply unit, and there are no controls — manual or automatic — either.

USB 3.0 ports from the front panel are connected by a monolithic block to the system board, there are no adapters for USB 2. 0 and the ability to connect to the ports on the rear I / O panel. The block for connecting the audio connectors is also monolithic, supporting the HD Audio standard without backward compatibility with AC’97. Buttons and indicators from the front panel are connected with a standard bulk of separate wires.

Noise level measurement

Noise level measurement is carried out in accordance with our method using the Oktava 110A-Eco sound level meter in a soundproof room with a typical noise level of 20 dBA. During the measurement, all electrical appliances in the room are turned off.

An autonomous controlled converter was used to regulate the supply voltage of the fans.

Chassis cooling system noise ranges from low noise when powered by a 5V fan to moderate noise when powered by 12V. A source with this level of noise will be less noticeable in typical daytime living environments days. At night, at minimum speed, the cooling system of the case will also not cause concern from a distance of a meter or more.

Testing the effectiveness of the case ventilation system

This stage of the study is testing using software tools that load various subsystems of the computer, which, in turn, causes a fairly powerful heat release. Thus, you can evaluate the capabilities and performance of the cooling system of the case.

The test bench configuration included the following components:

  • Motherboard Asus P8H61-I LX

    • Idle — running Windows 7 Home Premium with MS Essentials antivirus enabled and running background processes for 1 hour.
    • Video (CPU) and Video (DXVA) — View a Full HD (BDRemux) movie using VLC 2.0 player with the hardware decoder turned off and on for 1 hour.
    • LinPack — load of the central processor with calculations in the Intel benchmark program for 1 hour; this software is famous for creating an unusually high load on the CPU, warming it up to the maximum level.
    • FurMark — load of the graphics accelerator and, to a lesser extent, the CPU in a specialized benchmark for 1 hour.
    • FurMark + LinPack — simultaneous launch of both benchmarks and their run for 1 hour; here the load on the PC components should be maximum.

    The test results are shown in the diagrams:

    Testing clearly proves that the standard cooling system of Corsair Obsidian 250D is poorly suited for building a PC with a passively cooled video card. The case fans are too far away from its heatsink, which becomes noticeably hot at times of high load.

    The hard drive cage is in a relatively cold zone, the drive temperature remains almost unchanged regardless of the test being performed and the speed of rotation of the case fans.

    When the supply voltage of case fans drops to 5 V, their efficiency noticeably decreases, but this seriously affects only the cooling of a video card without its own fan, and in general, a standard cooling system will still be enough for most configurations. Of course, it would be much more convenient to be able to adjust the fan speed in automatic mode, but here you will have to resort to the hardware capabilities of the installed motherboard and use specialized software like SpeedFan.

    Positioning and conclusions

    The manufacturer itself positions the novelty in the Obsidian line as a compact solution for those who do not want to lose the usual powerful components of a full-size PC, but at the same time are limited in free space. In fact, the body of the Corsair Obsidian 250D occupies even more usable space than the average miditower, and finding a good place for it will not be so easy.

    But if the issue with the installation location is resolved and does not cause unnecessary difficulties, then the Obsidian 250D can be used to build a PC of any category: from a simple HTPC to a powerful gaming platform. The only thing the case is not the best for is creating a home file server with a large number of disks. Still, only two full-size drives are relatively small for a full-fledged NAS. In addition, we note the undesirability of installing video cards with a passive cooling system in this case: you will have to make serious efforts and, probably, sacrifice silence to provide decent cooling for such a configuration. But with powerful video cards with a full-fledged cooler, no problems should arise.

    Assembling a PC in this case is extremely pleasant, all steps are simple and intuitive. The system of quick-detachable dust filters evokes only positive emotions, the workmanship, design and cooling system also do not cause any complaints. We think this model deserves the Original Design award for its unconventional approach to chassis design and stylish «cubic» design.

This material is dedicated to the Corsair Obsidian 250D case, the smallest and most budget representative of the Obsidian line, which was born in January 2014.

It is made in the Mini Tower format and is designed to install motherboards of the Mini-ITX form factor. The latter are becoming increasingly popular today, as are compact cases. Therefore, the release of such a solution, especially under a well-known brand, attracts increased attention from the public.

The older Obsidian models (350D, 550D, 750D and 900D) that have been in our laboratory before have left only positive impressions. Let’s hope that the manufacturer did not let us down with this «baby».


The Corsair Obsidian 250D boasts support for a full-fledged power supply, long graphics cards, a large number of fans, including a 200mm giant, and a 240mm liquid cooling radiator. The case opens from several sides, which provides easy access to components, and is equipped with a stylish transparent window on the top panel.
