Corsair 800D has five 5 ¼” bays, all featuring screwless mechanisms, and six 3 1/2" bays for hard disk drives. Four of them feature hot-swap connectors, meaning that you don’t need to install any kind of cable to your hard drive: just install each drive inside a drawer and lock the drawer in place (of course you must connect the hot swap connectors available inside the case to your motherboard and power supply). All the four hot-swap bays from Corsair 800D also support 2 1/2" devices, which is terrific, allowing you to easily install SSDs.
