Well, on both 180s, right where the Screen Display cable meets the motherboard, the case has a slight bulge on the bottom.

No matter what I try to do, this stays.

Also, on a FYO note, the highest failure rate SCSI drive out of my powerbooks is the 120mb IBM. All of them are dead. The 80mb IBMs all work. I have not tested the 40mb Conners yet.
