NAS or Windows with network storage?

I currentlymhave Media server running on an old PC which generally serves me fine. I have multiple usb drives storing my files and want to upgrade my system.
I was going for. NAS server with integral storage but am now thinking thisnis overkill for my use. I have seen a nice mini pcmwith an i5 orocessor and a 20tb usb drive,
I mainly watch on my own network with family members also watching

Any suggestions which would be better for me?

I have been running Plex on unRaid NAS built out of older pc’s for years now and find it to be the best solution for me. Docker containers are pretty easy to learn how to set up and automate your downloads. I am running it on a old Core™ i5-4430 CPU with no issues but do keep most files limited to 1080p and have a few users who stream outside of my home

Thanks, will take a look.
