I built a Windows Home Server recently. It's mostly intended as a 5 TB bit bucket for DW's HDTV 'collection.' It sits in the basement with no keyboard or monitor, just a wired network connection.
It has additional benefits. It automatically backs up all networked computers each night. The file server makes copies of all photos and other irreplaceable files on 2 separate hard disks. And, it comes with a domain name that makes it accessible from the internet via HTTPS.
You can build your own now with OEM software or look for the commercial products becoming available. Enthusiasts have built servers with junk parts lying around.
