I use such a computer to expose services from my home server. You can do this using tailscale or even rathole. (Sadly, I don't have access to the router to port forward packets to my home server directly.)
Things I like to host: Jellyfin, Audiobookshelf, Karakeep, Deluge, Tailscale (for exit nodes, among other things)
Other stuff I want to host but not yet: Immich, Vaultwarden, Hister, Archibebox, CopyParty
