The epia-boards are still around and being upgraded. If you really want
something small and energy efficient, you could take a look at the
pico-ITX and nano-ITX boards from VIA. They give you sufficient processing
 and graphics performance for a car computer or even a myth-box (FullHD
could be a wee bit tricky) and fit into the space of a 3,5"-HDD. They are
a litte overpriced, though.
