I have a synology and really love it for storage-based use-cases: local machine backups, photo library, media server, gitea, etc. It's primary purpose is storing my lifetime of photos, which also get backed up periodically to a Borg cloud service.
I use Umbrel for bitcoin/lightning, and a full-on cloud VPS for all my other self-hosted stuff (including a nostr relay). I guess i have an relay on the umbrel, too, but it mostly just mirrors all my notes as a kind of backup to my VPS personal relay.
