Corsair is known for its large, roomy enthusiast cases, but it hasn't dabbled in smaller form factors. That's changing today with the new Obsidian Series 350D, which is Corsair's first enclosure designed to fit microATX and Mini-ITX motherboards exclusively.
Despite its compact 17.7" x 8.3" x 17.3" dimensions and lack of support for full-size ATX mobos, the Obsidian Series 350D has plenty of room for storage, expansion, and cooling. Users can fit up to two 5.25" optical drives, two 3.5" hard drives, and three 2.5" SSDs. The hard drives slide in at the bottom on removable trays, while the SSDs go in a separate cage near the top. That SSD cage is fed from the right side of the enclosure to simplify cable management.
The gap between the 2.5" and 3.5" bays leaves room for up to two "full-length" graphics cards. To keep those cards (and the rest of the system) cool, Corsair lets you install two 140-mm intake fans under the front panel. The company also leaves room for three exhaust fans: two 140-mm ones at the top and a 120-mm spinner at the rear. Users with more exotic cooling needs can even forgo the top exhausts and install a 280-mm radiator in their place.
Out of the box, though, the Obsidian Series 350D keeps things simple. It comes with only two fans: a 140-mm front intake and a 120-mm rear exhaust.
This enclosure has some of the same conveniences as its bigger siblings. There are USB 3.0 front-panel connectors, rubber-grommeted cable routing holes, tool-less drive mounts and thumb screws, removable dust filters behind the front intakes and under the PSU, a big cut-out in the motherboard tray behind the processor, and so on.
The 350D will be available next month in two flavors. A windowed model will sell for $109.99, and Corsair will offer a plain variant priced at just $99.99. That will make the 350D not just Corsair's smallest enclosure, but also one of its most affordable models.
