The Bottom Line

Jan 4 2016 - The Corsair Obsidian 250D may not be the smallest mini-ITX case on the market but it is designed to offer the potential for full size and performance components in a smaller than traditional size. It does this job extremely well with lots of airflow and cooling options to keep a high performance system running properly with little noise. Overall, it is a well built and designed case as long as you don't mind it being fairly large compared to many others.

Review - Corsair Obsidian 250D

Jan 4 2016 - Small form factor systems are becoming very popular for those that have limited space in their home or want to try and integrate a PC into their home theater system.

Corsairs's Obsidian 250D is much larger than many other desktop systems designed for the mini-ITX motherboard standard as it uses a cube style design that allows it to have more airflow and space for high powered components, traditionally a problem for small form factor designs.

The case is under a foot wide and eleven inches tall and has the depth of a standard desktop tower case.

Construction is a mix of steel for the base frame with aluminum front panel to give it a bit more of a stylish look. Rather than a single cover, it uses three panels for the two sides and the top to provide easy access to the components. All external screws use thumbscrews for easy tool-free access.

Internally, the case is divided into zones. The lower portion houses the space for a full size ATX power supply and the smaller drive cages. There are two removable trays that can be used for either 3.5-inch desktop size drives or 2.5-inch laptop hard drive or SSD drives. The front portion of the lower space provides plenty of room for power and drive cables to be out of the way of the upper components. The upper portion of the case features the standoff for the motherboard and the removable 5.25-inch drive tray. It should be noted that if you use the drive tray, it may restrict some space for the PCI-Express graphics cards.

Overall, the design offers plenty of cooling with the large 140mm fan pulling air in through the front and over the interior components. The bottom and sides also have grills to allow air for additional cooling. This means that graphics cards and power supplies can pull in fresh cool air rather than having to pull interior case air.

There is space for the two rear 80mm fans in the back and two 120mm fans on the size plus the front fan can be replaced with a larger 200mm if you so desired.

Now one of the big features with all the space of the Obsidian 250D is the ability to have internal liquid cooling solutions. Specifically, the Corsair case has been designed to be used with the Corsair Hydro H55, H60 or H100i closed loop liquid coolers. I tested it with the 100i GTX and noted that the fit is a bit tight as the hoses tended to either bump into the front fan or be pinched by the motherboard mini-ITX rear I/O components. It would not be possible to install it with an optional 200mm front fan.

The big question consumers will have is why limit yourself to an mini-ITX board for the Corsair 250D. It is nearly the size of many mATX cases and certainly much larger than most mini-ITX. What that extra space does for you is give you the option of putting get her an extremely powerful system that can effectively be cooled so that it is very quiet. It is not going to be totally quiet though as it does have lots of vents that also let out fan noise as well. But with the high volume of airflow, there is little need for high speed fans. The result is a somewhat large case with great performance potential for those that want something smaller than a traditional tower.
