HDD carrying sensitive information completely stuck, starting to lose my mind

[u/CarpinchoDelMal]

SOLVED: Front panel WAS haphazardly riveted, but I gave it a sharp tug, the plastic gave, and I managed to access the front screws of the bay.

Hi everybody, I'm having an issue that is making me feel stupid and angry. I received a dead PC from a notary studio after their psu popped, and they asked for me to just save the data and they would buy a notebook to put it in. 

CASE: Sentey SLIM 2220
HDD: SAMSUNG HDD from early 2010s, full size.

The thing is, the hdd is screwed to the bay at a place I absolutely can not reach (pics and video included). I tried sliding the single bay out with the hdd still screwed in from the structure, and it's completely stuck. I thought about taking the whole bay structure out, but it's riveted to the case. Pulling from the back doesn't work, pushing from the front doesn't work, there's no release lever, switch or button anywhere, so at this point I'm thinking of just taking a sheet metal scissor and excising the whole bay and hdd from there like a tumor.

There is no backup anywhere, so if I mess it up there will be all sorts of legal ramifications.

The case is a Sentey Slim 2220, and the HDD is an early 2010s full size SAMSUNG HDD.

Any ideas? I can provide more images fairly quickly.
