My media server also handles family movies, including VHS from the 80s I've converted and cleaned up.
Server itself is a cheap off lease dell micro I bought several years back for $125, added a $50 nvme SSD, and the igpu has been chugging along transcoding beautifully since.
Same system also runs a separate book/comic/etc service, backup DNS, a generated kid safe "channel" that is available on the media server, all my dslr photos are on there, etc, etc.
Which then for what is crucial to me gets a local and a remote backup.
At this point I've saved money over paying for subscriptions, and I use it for a whole lot more (so even more savings on top).
