Just found these while looking around for embedded systems.

Heck with my efi program....whos up for some Ubuntu-GS500's!  LCD and DVD drive optional

Mobo+cpu is around $70....

Already using one as basic foundation for GPS/Navi entertainment system build for my wifes mustang.

The touch screen monitor is the expensive part.

FYI solid state drives are out.

Cool... though i dont think it would be a good efi platform personally... what if you get some sort of error? or if it freezes or somthing...
