Well, I'd like to see if I can make something happen. 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...
