Yes. And No.

I have a home made (arch btw) NAS that stores all our files - mostly via syncthing, even from remote family.

That was it.

Then I installed Immich so that we could see the photos… so… it’s technically just a NAS, but it does now have a web application running on it…

Videos & Music are on a completely separate MythTV box which existed before the NAS - I saw no point in moving ~3TB of data to a separate box that would need to be powered when I want to watch / listen to something… my NAS powers itself up & down throughout the day to save electricity (and it was interesting to learn how to make it know when it was / wasn’t being used)
