I have this remarkable image in my mind of 20 or so lovely EATX
dual-opteron motherboards arranged radially like fins around 
a couple of heavy-gauge copper cables running vertically through 
a cylindrical rack, with a monster fan at the bottom.  it would 
be lovely, and perhaps even worthy of a cray-ish couch around it ;)

heck, such an arrangement could even cut down on that murderous
time-of-flight component in gigabit ethernet performance :)
