I also happen to have a spare mini pc. It was originally a Chromebox that I converted to a TrueNas server a few years back, then abandoned it after building my current server.
I want to put it back in use but I'm not sure what to do with it and I'm hoping to get some suggestions.
It has 6gb of ram and 128gb of storage. I believe the current OS is TrueNas core but I can boot pretty much anything on it. I was thinking maybe a small SMB share for my family though we don't really need it.
