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 introduced eary 2012, and fit-PC 4 was introduced spring 2014. The device is power-efficient (fit-PC 1 was about 5 W) and therefore considered[by whom?] to be a green computing project, capable of using open source software and creating minimal electronic waste.
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. 
On December 2, 2009, Compulab announced the fit-PC2i, a fit-PC2 variation targeting networking and industrial applications. fit-PC2i adds a second Gbit Ethernet port, Wake-on-LAN, S/PDIF output and RS232 port, has two fewer USB ports, and no IR.
The fit-PC3 has been released early 2012. See the fit-PC3 article.
The fit-PC4 has been released spring 2014.
On September 16, 2008, Compulab announced the Fit-PC Slim, which at 11 x 10 x 3 cm is smaller than fit-PC 1.0.
fit-PC Slim uses 500 MHz AMD Geode LX800 processor and has 512mb soldered-on RAM. The computer includes a VGA output, a serial port with a custom connector, Ethernet, b/g WLAN, and 3 USB ports (2 on the front panel). The system has an upgradeable 2.5" 60GB ATA hard drive.
fit-PC Slim has General Software BIOS supporting PXE and booting from a USB CDROM or USB thumb drive. It is pre-installed with either Windows Vista or with Ubuntu 8.10 and Gentoo Linux 2008.0 . Also Windows Embedded can be used, or pre-installed on a FlowDrive.
The fit-PC Slim end-of-life was announced on 19 June 2009 with the general availability of fit-PC2.
fit-PC 1.0 is an earlier model that has the following differences
- Limited to 256mb RAM
- No Wi-Fi
- Dual 100BaseT Ethernet
- Larger form factor - 12 x 11.6 x 4 cm
- Only 2 USB ports
- Hard disk is upgradeable
- No power button and indicator LEDs
- 5 V power supply
- Trim-Slice, an ARM mini-computer also made by CompuLab
- Industrial PC
