First off, note that the Obsidian 250D clocks in at nearly twice as much as other Mini-ITX enclosures, like the Cooler Master Elite 120. The 250D is not cheap, but leaves the competition behind because it is more compact and of better build quality, comes with nearly no compromises in terms of component size and functionality, and has the ability to hold a 240 mm liquid-cooling unit. All those points and the inclusion of two retail quality fans simply justify the Obsidian 250D's price. It is great to see that Corsair has managed to offer a case of this size without of the usual compromises associated with Mini-ITX cube enclosures. You may install long GPUs and PSUs and above-average air cooling in combination with a fully sized 5.25" drive. The chassis can also hold up to four hard drives without any issue at all. These specs read like those of a tower chassis, but the Obsidian 250D is extremely compact. Corsair has done so through creative engineering and by going that extra mile when it comes to the small details. Such include the locking mechanism of the ODD drive or the 5.25'' drive bay bracket opening right above the GPU's power connector. Corsair has even managed to place removable dust filters on both sides and the floor while keeping the top free for a spiffy little window. Odds are you want to show off the potent components within the tiny Corsair Obsidian 250D—a small chassis with a huge punch.
