i'll try again. after more thorough searching, i've realized that a cheap ups backup won't work with a g5 powermac, especially with some extra hard drives and such... does anyone have experience with any particular ups system with a g5 powermac? how does this one look? http://www.newegg.com/Product/Product.asp?Item=N82E16842101006 or do i need to go with 1500 VA? any help would be great.
