Better yet, run your home on Dell/HP micro computers that get decommissioned by enterprises/hospitals/big-orgs every 3 years. Find them on Offerup or FB or Craigslist market place for $100-$200. These are built solid with metal enclosures, fan cooled, UL certified PSU, ~7k CPUbenchmark.net. Usually i5 6thGen Intel CPU, 8GB-16GB RAM and have REAL storage(SSD) and M.2 NVMe. If you are lucky you might find vPro version…
I did that too but those PCs are just stupidly massive for the purpose. Raspberry Pi 4s don’t require SD cards any more so the storage issue is moot. My RPi sits next to my router now, you wouldn’t even know it’s there unless you looked closely.
Some brave souls have installed Home Assistant on their routers: https://www.snbforums.com/threads/home-assistant-entware-gt-...
