The case is roomy enough for ATX/XL-ATX/EATX/HTPX motherboard form factors and features various cut-outs to make cable management easier. There are three 5.25" drive bays, two detachable 2.5/3.5" bay cages with three slots each as well as four other 2.5" bays behind the motherboard tray. Pricing is anticipated to be around the $249.99 mark.
Moving on to its ventilation system, the Obsidian 750D features a detachable front panel, which reveals a front intake with room for two 120 mm fans (included). With a little drive-bay management inside, you could create room for a 240 x 120 mm radiator at this spot. The rear panel includes a single 140 mm exhaust (included). With the drive cages moved to below the 5.25-inch ones, you get two 120 mm intakes. On the top, you get room for either two 140 mm or three 120 mm exhausts. Front-panel connectivity includes HD audio jacks, and two each of USB 3.0 (standard header), and USB 2.0/1.1 (standard header) ports.
