This case has four external 5 ¼” bays and six internal 3 ½” bays. All 5 ¼” bays use screwless mechanisms that look very differently from traditional mechanisms used by other brands, but they work very well, holding 5 ¼” devices very tight. The lower 5 ¼” bay comes with a 5 ¼”-to-3 ½” adapter, allowing you to install up to seven hard disk drives if you don’t have a floppy disk drive or memory card reader and won’t be using all 5 ¼” bays.

The hard disk drive cage can hold up to five hard disk drives, using a screwless mechanism based on two rulers that must be installed to each side of the hard disk drive. A small toolbox comes installed on the top bay and can be used to store screws and other small parts. A sixth bay is available between the hard disk drive cage and the 5 ¼” bays, but this bay does not have any sort of screwless mechanism.
