Steve,
I know I asked which motherboards you are using, but I am really curious
to know more about the setups you are using. For instance, what cpu do you
use (can you get away with a heatsink only to eleminate all moving parts)
What do you do as far as RAM, have you found nice small form factor cases to
use, etc. etc. I think this may be the way we should consider building out
our new network.
