heh, i've seen this thread here a few *cough*hundred*cough* times before
All that stuff above is all true, but you might try mineral oil. I don't know how well it would work as a normal pumped coolant, but it (supposedly) worked for the immersed case the OCZ made. You could just go for a liquid immersed cooling system, completely safe to equipment, not prohibitively expensive. Only two problems I can see are leakage and not being willing to lug 200 pounds of mineral oil to a LAN
