This is what actually started this madness BTW:

I do have a tualatin kicking around from a Shuttle SV25 that has a bad
motherboard (the caps leaked). It even has a 1U heatsink/fan
combination to save room
. My plan is to get a 1U case, see how much
of a headache the AMD64 board and processor is to set up. Worse case
senario I can put the AMD64 combo in a generic InWin tower that I have
kicking around and go socket 370 for the 1U.
