NeXT Cube
The NeXTcube was a high-end workstation computer developed, manufactured and sold by NeXT from 1990 until 1993. It superseded the original NeXT Computer workstation and was housed in a similar cube-shaped magnesium enclosure. The workstation ran the NeXTSTEP operating system. It is famous as the world's first Web Server, used by Sir Tim Berners-Lee at CERN to create the first web page on December 25th 1990. [source]
