This AEC-7730A SCSI - SATA bridge was about the price of a decent PC GPU, but sticking a Samsung 860 into my original-owner A3000 is a completely perverse joy.
Now there’s ancient stuff from about 500 floppies from the 80’s and early 90’s that display in seconds, and although its pretty much a Turing machine for some things OS4 it does run Odyssey and Workbench Explorer well enough (it also has a Radeon + one of the last available Mediator 3000D’s, + BigRamPlus / X-Surf-100+USB).
Way overkill but this thing is serious fun to use, like it's 1992 all over again.
