Back in the early '90s I worked at a PC builder. They got in a batch of drives that had their PCBs closer than usual to the screw holes and installed quite a few before they noticed. They tried to RMA the drives, but were refused. In the end the got a bunch of shorter screws for those drives. They were a fairly large local business, but they priced out big quotes for the University based on the price of parts dropping over 3 years, and then one year in the late 90s prices went up rather than down, and it suddenly put them out of business.
