I just use a laptop at home though I have a raspberry pi buried in some junk that I was using as a tv typewriter for a while. I have a Hetzner dedi and a bunch of random VPS to use as servers, and my backups are on Hetzner Storage Box. That's partly because I don't have much space at home for machines, and also because my home internet is crap. If you've got the space and bandwidth for it and cheap enough power though, then sure, why not go for it.
