Current models.
fit-PC2.
On February 19, 2009, Compulab announced the fit-PC2, which is "a major upgrade to the fit-PC product line".
Detailed specifications for the fit-PC2 include an Intel Atom Z5xx "Silverthorne" processor (1.1/1.6/2.0 GHz options), up to 2GB of RAM, 160GB SATA Hard Drive, GigaBit LAN and more. The fit-PC2 is also capable of HD video playback. Its declared power consumption is only 6W, and according to the manufacturer, it saves 96% of the power used by a standard desktop. fit-PC2 is the most power efficient PC on the Energy-Star list.
The fit-PC2 is based on the GMA 500 (Graphics Media Accelerator). Unfortunately the open source driver included in Linux kernel 2.6.39 does not support VA-API video or OpenGL/3D acceleration.
