kanewolf,
What do you think about this one?
APC SURTA1500RMXL2U On-Line Smart-UPS 1500VA 1050W 120V Rackmount w/New Batterie
Would I still want to replace the battery?
At 1050W, I think it could handle all 3 machines plus maybe my computer, 2 monitors, printer, right? I haven't looked at wattage...
