Deja Vu!
I had almost exactly the same thing happen to one of the machines that I was supporting in a job long, long ago and far, far away!
The fan heater under the desk was 'kicked' away when someones feet had warmed up ...... to directly face the front of a PC with a 5.25" floppy drive. It was nowhere near as sagging as the one pictured but I think the heater was only on medium rather than high.
Within the floppy drive there was a plastic fork/guide that would sit either side of the floppy when it was inserted, and this was left with a serious case of brewers droop! Which was discovered the next time a floppy was (attempted to be) used to sneakernet some data from that machine.
The fix was to extract the drive, then have a cow-orker apply pressure to the forks, holding in the correct position while I applied a hair dryer to soften them. It w**ked fine after that. And the PC was moved to a shelf, out of range of the offending heater.
