Get a Raspberry Pi 4 and install https://umbrel.com on it. Easy to set up using Tailscale and optional TOR support if that's something you want. And it has all the "important" stuff like Nextcloud, Vaultwarden, Pi-hole, Matrix server, etc.

There's a bunch of Bitcoin related Apps as well but it's easy to just ignore those.

Full list of "apps" here: https://github.com/getumbrel/umbrel-apps
