do you want 8 backends or 8 capture cards? One of the dual core machines 
would be enough to serve as backend for 8 DVB/ATSC cards if you could 
connect them all. Depending on what you want to receive you don't even 
need 8 cards.

Your plan seems to miss some facts. Why do you want to use 8 frontends 
if you have only three hdmi connections? I doubt anyone would want to 
use a frontend in a single room with all those computers above.

Please send a more detailed plan of that you want to do.

Probably a couple of meters but there are ethernet capable lirc devices.
