It's under $100 and it's already available.
A lot of products at CES are unveiled sans release date. It's also not very common for a product to be available immediately. Still, there are exceptions, and this year, Corsair's Obsidian 250D Mini-ITX case is among them.
The Obsidian Series 250D performance Mini-ITX PC case is available immediately and is Corsair's first chassis built for the Mini-ITX form factor. The 250D supports all modern ATX PSUs (200 mm of PSU clearance) and boasts two expansion slots, (290 mm of internal clearance), two tool-free 3.5-inch/2.5-inch combo bays, two tool-free 2.5-inch only bays, one full-size 5.250-inch drive bay, and two front-mounted USB 3.0 ports.
As far as cooling is concerned, you're looking at two high-airflow fans with room for up to five fans. Radiator compatibility is 120 mm or 140 mm up front or 120 mm or 240 mm for the side.
The side panel and expansion slots utilize thumbscrews, and the case features easily accessible and removable front, side, and PSU dust filters. There's also cable routing with multiple tie-down points to keep everything neat and tidy.
The whole thing weighs 9.7 lbs and is priced at $89.99.
