How many surge protectors/battery backups do you have in your den/computer room? And what are you plugging into them?
I currently have just put in my 4th surge protector
. The room is fairly small (I'd assume around 9x9) and it has to house the 37" HD rear projection tv, 2 smaller 20" SD TVs, Gamecube, Xbox 360, playstation 2, intel iMac, 17" LCD monitor, slow windows box, router, modem, telephone, printer, SNES, VCR, Satalite box, surge protector and probably some things that I completely forgot about.
