If you are buying used datacenter drives, larger capacity drives are also likely to be newer, which tips the scales a little more in that direction.

Seconding Plex / Plexamp if the use case involves streaming remotely. Probably the easiest to get up and running for remote access.

I’m not sure about the capabilities of hosting on a Pi, but it should be straightforward to run a couple different apps in parallel to test and compare features (I’m currently doing exactly that with Plex and Jellyfin)

This one took me a second… 😆
