14 DAY TRIAL // Full ATX desktop cases used to be the largest type, but now there are larger ones, E-ATX form factors. The only ones that can fit extended-ATX motherboards.
Xigmatek has just announced the Assassin series of E-ATX cases, composed of both black and white models with or without side windows.
Verily, one may simply call Assassin a single product with various color and side panel options.
It measures 210 x 500 x 500 mm (WxDxH), or 8.26 x 19.68 x 19.68 inches.
It has three 5.25-inch bays (surprisingly few, really), eight 3.5-inch bays, tool-free installation for ODDs/HDDs/SSDs/HHDs, and eight expansion slots for video, audio and LAN cards, or whatever else goes in PCI Express slots.
Xigmatek implemented valved flaps on the motherboard tray too, as well as a bunch of fans and enough room for graphics cards of up to 32 cm / 12.59 inches, and CPU coolers up to 16 cm / 6.29 inches tall.
