It's a small (100 x 160 mm) board, with
- AMD Geode LX800 CPU with 800 MHz
- 256 MB DDR DRAM
- Via VT6105M 10/100 Mbit Ethernet
- 2 miniPCI slots
- AMD CS5536 Geode companion providing 2 USB 2.0 ports, 1 serial port (RS232), 1 Compact-Flash slot and integrated VGA and audio
More information, datasheets and manual can be found in the Alix Wiki.
I ordered the board from Varia Store for about 130€ including an aluminium chassis and a suitable power supply.
Challenges are now to install an optimized Gentoo on a Compact-Flash card with support for all hardware included, installing a 802.11b/g/n WLAN card and doing some tests with my Logitech QuickCam Pro 9000.
