Embeded System Recomendation

I have been searching for a system that meets my needs, but I'm having alot
of trouble. I am looking for a low power consumption (will be on 24/7)
system that has a processor or 1ghz or more, 512m ram or more. I also
would prefer that the system have a gigabit network card but an open pci
can take care of that for me. I am also looking for serial ata ( will be
used as a file server running FreeNAS (http://www.freenas.org), but ide
only is fine too as long as there is another open pci slot. Any
recomedations?
