Incidentally, I built something for exactly this use case and just posted it as a Show HN: a mini PC that ships pre-loaded with OpenClaw (an open-source claw runtime) and runs at 15W for always-on deployment. The idea is to remove the friction of "set up a VM, install the framework, keep it running" for people who just want a persistent claw at home.

Happy to discuss the hardware tradeoffs if anyone's gone down this path.
