This case has four external 5 ¼” bays, two external 3 ½” bays and four internal 3 ½” bays. The external 3 ½” bays can be used by hard disk drives if you don’t have floppy disk drives or memory card readers installed, so you the maximum number of hard disk drives you can install is four, five or six, depending whether you use the external 3 ½” bays or not.

The disk drive bays don’t use any kind of screwless mechanism for fastening disk drives. Rosewill website says “Tool-less design,” but this is incorrect. The internal 3 ½” bays have a plastic holding mechanism, but it isn’t screwless. You need to add rounded head screws to the front holes from each hard disk drive and this can only be done by using a Phillips screwdriver. Then you slide the drive and the mechanism will lock the drive into place. Or sort of: the drive will be still lose so it’s better if you add a real screw to the rear holes from each hard disk drive. For the untrained eye the presence of these plastic holders for the hard drives can be deceitful, as you may think they are part of a screwless mechanism.

This case has another 120 mm fan between the hard disk drive bays and the front panel. This fan however uses a standard 4-pin peripheral power plug, so you can’t monitor its speed.
