GScube

The GScube was a hardware tool released by Sony intended for use in CGI production houses consisting of a custom variant of sixteen PlayStation 2 motherboards running in parallel. It was unveiled in 2000 at SIGGRAPH; the name "GSCube" is short for Graphics Synthesizer Cube. It was used for two projects, Final Fantasy: The Spirits Within and the film incarnation of Resident Evil.

According to some sources, they were all sent back to Sony in Japan and were subsequently dismantled. They were used for prototyping visual rendering in Final Fantasy, The Matrix and Antz, as well as in a flight simulator. Although the GSCube had good rendering capability, they had a major bottleneck in connecting to external computers to transfer content.
