Hi, I just bought a refurbished Rev B iMac G5, and am looking at covers for when I'm not using it. Normally I wouldn't be so anal, but the only option I have in my bedroom is to put it next to a big window which brings in a lot of sunlight. While the blinds will be closed while it's in use, I guess I was concerned about having the whole system up on the desk when not in use (used to have a G3, on the floor). The back of it is facing the window. Anyone use a cover? Do they cover the back too? Any suggestions?
