I have been running a mac mini as my "server" for 6+ years. I like that it has more functions that a nas. Having a TB hub connected with 8 4 TB drives connected. So are backup drives and I only turn them on once a week for backup. Another plus for this system is there is no one point of failure. If the mini dies I can move one or any drive to a mac to access the data. I also have 2 VM running Pi hole and VPN software to name a few.
The only thing ng that is wrong with that is technology changes! You probably will have to find cable adapters when you finally join the modern age!
