This case has five external 5 ¼” bays and six internal 3 ½” bays for hard disk drives, all using a screwless installation mechanism based on rulers that need to be installed on the sides of each drive. The installation is simple: just add two rulers to the drive you want to install (see Figure 17) and then slide it in the bay you want to use.

Maelstrom also comes with a 5 ¼”-to-3 ½” adapter, allowing you to install a 3 ½” external device like floppy disk drive or memory card reader to any 5 ¼” bay. This adapter supports also the installation of a hard disk drive on it (it has the appropriate holes), so you can have up to seven hard drives installed if this adapter is used.
