This case has nine external 5 ¼” bays, coming with adapter pegs for one 3 ½” device. It also comes with a hard disk drive cage supporting up to four drives. This cage takes three 5 ¼” bays and you can install it on any three bays you want, it doesn’t have to be the lower three bays, even though this is the most common configuration.

So if you don’t have a floppy disk drive and have only one hard disk drive you can install up to eight 5 ¼” devices, by removing the hard disk drive cage and installing the single disk using the four pegs that come with the unit. If you have a floppy disk drive then you have to use the hard disk drive cage. In this scenario, which is probably the most common one, you have five 5 ¼” bays, one external 3 ½” bay and four internal 3 ½” bays.

This case does not implement any kind of screwless mechanism, so you have to use screws to fasten all drives (and the hard disk drive cage) to the case.

It also doesn’t bring any kind of mechanism for reducing the noise produced by the hard disk drives.
