The rear left corner at the bottom of the casing was dented; obviously, the device had suffered damage from a fall. The chassis and the cover lid were affected. There was also another deep dent at the front of the lid, topside, near the bezel.
The floppy drive lever was missing, and the chassis was covered in old adhesive residue. The graphics card’s slot bracket was not fastened because the threads on the connector were broken off and the port hex screws were missing.
