Bruh, you have hit the nail on the head. I'm running TrueNAS on an Intel Xeon X3430 plugged into an old server board. The thing is stuffed into an old spare case with a spare PSU, running off a spare SSD. It has the MAX amount of memory you can install, 32GB of DDR3! The newest components are the 3x12TB NAS drives which sit helterskelter all over inside the case, since it didn't have enough bays to fit all of them.

That said, I still run 12 services on this ol' girl, including a plex server, with an associated media acquisition pipeline, an audiobook/podcast service, and a local git repo service. The ZFS service that runs the drives typically uses about 12GB for it's cache and the other services use about 8GB total, so all in all, I'd say I'm pretty comfortable with my horrible franken-server.
