If you can avoid having you server and the media library on separate systems you should. That means buying (or I suppose building, but I wouldn’t recommend it) a NAS with sufficient processing ability to stream / transcode as much as you need, or stuffing a lot of storage into your mini PC.
One of the problems you’ll run into if you use separate systems is that it’s non-trivial to get the server to automatically notice new items in the media library and update to include them. I’m sure there are others.
