I ran the numbers on this hardware (I was curious), and it's rather expensive. I fired one up (running OpenBSD) just to see what the actual draw was under load, and it's huge. 2.243kW per machine. Not counting the cooling load, we pay $0.06/kW-H here, and that works out to $193.54/month to simply power both of them. At 11.3kBTU/h in heat output, these will consume roughly 2 tons of cooling capacity... Erich M. Jenkins Fuujin Group Limited "You should never, never doubt what no one is sure about." -- Gene Wilder
