Thanks, Jerry. I found two hidden screws under them and opened it up.
The ventilation of this drive doesn't seem to be very good because the
case has almost no openings, and the IDE drive inside has a metal cover
over its PC board that blocks all air flow. I'm thinking of
drilling holes in the cover.
