The cover comes off with 3 screws, two at the bottom corners, one at the cable
access door in the back. Pry CAREFULLY in the area of the handle to finish getting
the back off. The HD is them mounted in a cage dealie that has 2 or 3 screws which
are obvious for their locations. Remove the cage and drive and remove the card
edge conector when it allows.

By the way, unless someone has put in a secondary controller the HD is an IBM MCM
(ESDI essentially) drive. Easily found and up to 160mb capacity.
