My opinion after running a routing node on sub optimal hardware from home is a cloud based solution, but that has ongoing costs that you likely will not recoup from routing. If it's just for personal use with private channels to a few trusted and reliable peers it's fine for keeping the hardware at home.

I have an old desktop I'm thinking of converting to a start9 server and running a personal LN node. I don't have a clue how to do it, but I do think start9 looks better and more open than Umbrel, which feels like a bit of a walled garden.
