You can buy a used office computer from businesses that are upgrading (downgrading) to win11 for less than 50 bucks. They tend to be relatively low power, relatively quiet, lots of PCI slots and USB ports so there are many upgrade options, yet low entry price for a decent computer. If you plan on using as a jellyfin server: either mind the chip now for transcoding capabilities (there’s lists out there) or know that if you want that, you’ll have to put in a GPU at some point if the onboard can’t transcode well.

I have a mix of external and internal SSD’s. Some are running way not as fast as they theoretically could, but it all works well enough for me. You can start with what you have, storage is still expensive.

What’s the name of the app you tried?

the coordinates aren’t there i think, but there are github projects out there that “detect” the panels and suggest split based on that. For most of the panels of most of the comics, that would be more than enough to do a clean split. I just can’t find a real relatively easily deployable service that incorporates it.

The main mess is genres. That is non existent in the folder structure (I do have it: artist > albums), and still very hard with Picard etc. But genres is very convenient for Autoplay, auto generate shuffle playlists
