There was a run on Mac Mini's for people running OpenClaw earlier this year. I was doing some research earlier today on an idea and that came up as an option because it (and Apple's hardware for Macs) have shared RAM across CPU and GPU so its apparently a viable option to run ollama (ironically from Meta) or other local models for simple tasks.

I think VPS are going to be expensive because of the RAM and GPU requirements - 32GB RAM is beefy for a VPS and might run like $30/month on the cheap end. Thats $360/year so running something at home might be more secure, capable and cheaper. Remote/mobile access might be viable with something like tailscale.
