Closer Look: Exterior
While the Corsair Obsidian 250D mini-ITX computer case is indeed a mini-ITX case, it’s a rather large and chunky mini-ITX case. Check out how it appears next to one of my favorite mITX cases, the Cooler Master Elite 120:
Both cases have a full-sized 5.25″ bay and accept standard ATX power supplies. Why is the Obsidian 250D so much larger?
The front view shows us a brushed aluminum faceplate, the USB 3.0 and audio ports, and the very subtle power and reset switches to the left of the 5.25″ bay.
Both sides of the case have these large filtered vents. For this side, it means a good supply of cool outside air to your graphics card.
At the rear of the case, we can start to see some interesting things. The ATX power supply mounts below the motherboard, and there are mounts for two 80mm fans above the motherboard. Note that the space above the motherboard is limited compared to a full tower case; “big air” coolers aren’t going to fit. Corsair doesn’t specify the clearance for a cooler, but I measured it at about 140mm.
At the bottom of the case, there’s a pull-put, fine mesh filter for the power supply air intake.
Let’s continue our look at this case in the next section.
