Outrigger Macintosh

The Outrigger is a style of Apple Macintosh desktop computer case designed for easy access. Outrigger cases were used on the Power [Macintosh 7200], 7300, 7500, 7600 and Power Macintosh G3 Desktop computers from August 1995 to December 1998.
The logic board is mounted at the bottom of the case, with drive bays and a power supply in a separate fold-out section that swings aside as one piece and props open. This allows unfettered access to logic board connections such as the memory, Central processing unit, VRAM and drive/power connections without a screwdriver. The PCI slots were located on the left edge of the case and covered only by a plastic shield, making them accessible without lifting the drive bay assembly.
Apple's next Power Macintosh case design as used in the Power Macintosh G3 would also provide easy user access.
