A half rack server in a basement isn’t going to consume a lot of power or generate that much noise. I have home servers and they are fine.

I have home servers, designed for home and they are not too bad, and I can turn them off when sleeping for example.. It's very different with a 20U server running and spinning non stop. Not many people will have the soundproofing to simply not hear it at night.

I don't know, I wouldn't see it working, but I'm just one.
