Fit-PC
The fit-PC is a small, light, fan-less nettop computer manufactured by the Israeli company CompuLab.

Many fit-PC models are available. fit-PC 1.0 was introduced in July 2007, fit-PC Slim was introduced in September 2008, fit-PC 2 was introduced in May 2009, fit-PC 3 was introduced in early 2012, and fit-PC 4 was introduced spring 2014.  The device is power-efficient (fit-PC 1 was about 5 W) and therefore considered to be a green computing project, capable of using open source software and creating minimal electronic waste.

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.
The fit-PC2 is being phased out and is being replaced by the fitlet, the fitlet was designed to replace the groundbreaking (and still popular) CompuLab fit-PC2.
