I have been using an old PC as NAS and running docker containers (Immich, Nextcloud, paperless-ngx etc.). I got 5 3.5" HDD disks and a Nvme. Even on idle, I am consuming 50-60w. A friend of mine is selling a Qnap NAS which is a dedicated machine and probably consumes less power, although I don’t know if it’s worth it.
“powerful” LOL it’s a turd

but yeah my current setup also happens to play games and adding storage is much easier cuz I can just throw whatever in there instead of making sure the drive conforms to some arbitrary crap.
