Abstract: A computer case having at least one 31/2" drive housing which can be removably mounted within the case. Each 31/2" drive housing has one or more (typically, two) channels. A 31/2" drive is slidably insertable within each channel. A plurality (normally, as many as four) 31/2 drive housings are removably mountable at different locations within the case via quick release connectors provided at different locations within the case. A "U" shaped mounting bracket captures each 31/2" drive. The bracket has two opposed legs, with one or more inwardly projecting pins on each leg. The pins slide into apertures located in the opposed sides of industry standard 31/2" drives. A one-piece backplane with quick release connectors is easily removed and replaced by adjacent a cutout provided in an outer wall of the case. A series of cutouts are provided in the backplane. Each cutout is positioned to align with a connector on a motherboard mounted in the case, when the backplane is in place adjacent the case outer wall cutout.

Abstract: A personal computer case having a rectangular front panel with a pair of long sides and a pair of short sides. A drive housing can be attached to the case in either a desktop position in which drives mounted in the housing extend parallel to the front panel's long sides; or, in a tower position in which drives mounted in the housing extend parallel to the front panel's short sides. A separate control panel can be attached to the drive housing, parallel to the drives. The drive housing has a square cross-section sized to receive the control panel and a plurality of industry standard width drives stacked atop one another. Preferably, the cross-section is sized to receive the control panel and up to three industry standard 51/4" wide drives stacked atop one another. The front panel has an aperture with the same cross-section as the drive housing. The drive housing is positioned behind the aperture so that drives mounted in the housing remain accessible through the aperture.
