I remember videos (on youtube likely) of thermal paste replacement, that was upgrade to stock card. So, average person should be able to do it. It'll cost a few $$ for the paste. I would go with local workstation, then don't have to think much about while running stable diffusion. Plus, if it's used from ebay, prices cannot go much lower, you'll get something back at the end. Also, for image things training dataset can be quite big for network transfers.
