The other heating blanket had a mechanical issue.
But the driver had already killed its dropper capacitor a while ago. This is a replacement. Those To-92 parts are the thyristors that switch the mains voltage through to the heating elements.

The hard drive is a full height 3.5" affair, probably ESDI. But with this weird card edge connector. This is probably the only computer line that ever used these. So, there won't be a replacement for it.
I see lots of dirt, an empty CMOS battery that needs to go and a few of those explosive tantalums.

This thing is already a pain in the neck to work on. The board is held on by this screw which cannot be removed without also removing the plastic back
Alright, so the front and the white half of the drive bay is one plastic piece.
And underneath are plastic clips (red) as well as metal rods (blue). Once this thing snaps into place it's near impossible to take it apart again non destructively. Oh and the PSU is riveted in place.
