I'm considering to buy a SFF PC to act as a docker host. The main services / applications I'm going to run is going to be Immich. Filebrowser, Samba-share and eventually Paperless-ngx. I've been eyeing PCs with a N100 / N200 specifically to run quiet, and to conserve on energy consumption. I am most likely going for an Asus PN42 and will have an SSD in it to keep the moving parts to a minimum.
To those who are running machines with this CPU and similiar workloads, how has your experience been?
I can tell you that my Celeron J4105 (the N100's predecessor) can run paperless and most other NAS/home server tasks just fine. I haven't dabbled with Immich and its ML though. The 10W are pretty accurate. With hard drives, HBAs and PSU inefficiency, my home server comes out to about 20W from the wall under full load IIRC.
Also look out for RAM extensibility; you probably want 32GB in the not too distant future.
I've got a morefine m9 with an n100 in it, it handles nextcloud, immich, paperless, and much more without breaking a sweat.
I also chanced throwing 32gb in it and it runs fine.
I've got a beelink eq12 pro too with an n305 in it, and it handles all my plex transcoding etc.
Doesn't handle 32gb ram though unfortunately!
Both are very power friendly and work great with HDDs connected through external yottmaster enclosures through USB.
