I would suggest an Intel N100 mini PC if you are planning to transcode video files with Plex. Intel Quick Sync performs better than AMD for media transcoding.

Not sure if you’re aware, but Immich has a duplicate finder

Dockge for docker compose stacks. Glances for system resource usage because it has a Homepage widget.

I am running my disks as mirrors.

I have a Terramaster 4-bay DAS

I’m running a mini-PC with the N100, 12GB RAM, and 2x18TB mirrored drives on ZFS and it seems to work well.

I migrated using the CLI tool to upload before external libraries came out, and it worked well for me. I think I would have preferred to use external libraries for things like my wedding photos, so there aren’t duplicates on my server, but it’s not a big deal.
