If you’re looking for more compact than powerful asustor has this https://www.asustor.com/en/product?p_id=91 12 nvme sticks with 8tb per stick would give you 96tb of storage in that small form factor. Only problem might be how much power you’d get out of that processor but you can bump the ram up to I think it was 96 gigs

It’s kinda like an open source version of last.fm scrobbling. One feature they have that I was interested in was the weekly discover playlist.
