Nice! Do you do anything with that compute when you're not actively using it? Is the crypto-mining hobby still worth it? I've also wondered if such expensive hardware can be rented back out to offset cost. Looks like these cards are going for as much as $4k nowadays.
I've paid ~2k€ in 2023. Since I'm usually sitting next to it, I'm only using it when I want to use it. It can get quite loud and warm.
Crypto (to my knowledge at least) moved away from GPU mining. I guess you could maybe rent out GPU compute, but - being in germany - it's not worth the legal hassle. You could of course always commit tax fraud, though I wouldn't recommend that.

Massive legal liability. Not worth it.
There are services where you can hook your card up and rent it out to other users. I don't know what any of them are called, but they do exist.
