Painted the inside (you have to)..
My original goal was to just have a clear iBook. Once I achieved this it bugged me how ugly the glue looked that was holding on top frame and battery casing, although the glue did dry clear it was obvious it was there and looked horrible. So then I went out to paint it black, and achieved this but the paint did not work good enough, and kept rubbing off with the glue... So... I went back to making it clear again, and then went with Carl Norums looks with Red Paint.
