SGI O2 (R5000)

Originally known as the "Moosehead" project, the O2 features a proprietary high-bandwidth Unified Memory Architecture (UMA) that connects the various system components. A PCI bus is bridged onto the UMA with one slot available. It has a designer case and an internal modular construction. It has space for two SCSI drives mounted on special sleds (1 in the later R10000/R12000 models due to heat constraints) and an optional video capture / sound cassette mounted on the far left side.
