Hey Javier,

Yeah. I actually hadn't  thought of that. At some point I'm going to 
max out that power circuit... 8-(  I'd better see what that circuit's 
rated. Unfortunately I can only run all Sun and Mac boxes, routers 
cable modem, telephone adapter, laser and ink jet printer plus NAS, 
etc. on one circuit. I just hope that I never run it all at the same 
time. Ooops, air conditioner is rated at 9.85 amps. I'd better look 
at the circuit breaker.
