Restoring an old PC or making some cable spaghetti with some SBC is currently too advanced for average person.
Self-hosting for the masses would require some new form of home servers.
Something modular, where adding new components would be as easy as playing with Lego bricks.
Projects like Freedom Box were attempting this 10+ years ago, or even simpler, a home server that basically sits on your powerplug. AFAIK it sort of petered out fast, at least in the public mind, and I think it’s a shame. It had potential and was even more basic than the Lego approach.
