NeXT Computer
The NeXT Computer (also called the NeXT Computer System) is a workstation computer developed, marketed, and sold by NeXT Inc. It runs the Mach- and BSD-derived, Unix-based NeXTSTEP operating system, with a proprietary GUI using a Display PostScript-based back end. The motherboard is square and fits into one of four identical slots in the enclosure. The NeXT Computer enclosure consists of a 1-foot (305 mm) die-cast magnesium cube-shaped, black case, which led to the machine being informally referred to as "The Cube". It was launched in 1988 at US$6,500(equivalent to $13,000 in 2015).
