The SGI Fuel was released by Silicon Graphics in late January 2002. It uses the MIPS R14000A 64-bit processor, Ultra160 SCSI drives, and SGI's VPro graphics boards (Discussed in SGI Octane2). These graphics boards sport OpenGL on a chip (Only Fuel), and support 48-bit RGBA color.
The Fuel also hails the returns the internal CD-ROM drive option that was annoyingly dumped with the Octane and Octane2 design. The system's memory bandwith has a theoretical maximum of 3.2 GB/s and 1.6 GB/s between the graphics and system. Another add-on is an internal PCI bus which had to be external on the Octane as well. Of interesting note is that the Fuel includes USB ports, although at this time, they only support keyboards and mouses.
