@socketwench LibreELEC is really good at this.
I personally spun up Jellyfin though, there's a supported Kodi plugin and it handles everything like a champ. Pretty sure a spare Pi could handle it (I hope to cover this in a video soon, just need to finish the damn basement first).
@vkc House stuff takes *forever* especially if you're doing it alone.
I do have a miniPC I got from FreeGeek with LibreELEC on it. I should see about using that someday.
