Corsair announced its much-anticipated Obsidian 750D ATX full-tower case (model: CC-9011035-WW). Positioned between the Obsidian 800D the company debuted its case lineup with, and the Obsidian 650D, the case is designed to provide oodles of room for storage devices, long expansion cards, and enthusiast cooling solutions. To begin with, it measures 235 x 560 x 546 mm (WxHxD), dry-weighing about 9.5 kg. The primary material is steel, with brushed aluminium for the front-panel, and ABS for drive cages and other novelties.

The Obsidian 750D can house XL-ATX, EATX, and HPTX motherboard form-factors, in addition to common ATX types. The motherboard tray has valved cutouts for cabling/tubing at the right places, and a cutout around the CPU socket area, to help manage coolers better. The drive storage area is pretty modular. There are three fixed 5.25-inch drive bays, and two detachable 3.5/2.5-inch bay cages, which can either be arranged along the floor of the case to create more room for long expansion cards, or just below the 5.25-inch cage, to create room for longer PSUs, and fixed-cable spaghetti. Each 3.5/2.5-inch detachable cage can hold three drives. There are four other 2.5-inch bays along the plane of the motherboard tray, which can be access through the right panel.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. Corsair Obsidian 750D is priced at US $159.99.
