I started on a raspi but quickly upgraded to a small frame PC that I picked up used for cheap.

The services I find useful are: Tailscale, which gives me access to the server anywhere; Nextcloud for file storage, but also the music extension let's me take my playlists with me wherever; Nostr Relay backs up my Nostr activity automatically; Invidious for YouTube without ads or trackers; Audiobook shelf for podcasts and audio books; Jellyfin for movies and shows.

I actually run several other services on the same machine, just not through Umbrel. Tailscale, Pi-hole, Photoprism, Trillium Notes, Portainer, and recently Duplicati for back-ups. Some of these are available through Umbrel but I wanted more control over the services (eg Tailscale) or wanted to support the devs (eg Photoprism). 

 Thanks I was thinking the same. I have a mini PC but it limited on RAM and storage. I was thinking on switching to a regular PC as well.
you info is very helpful.
thanks again
