A probably very necessary upgrade is a new CPU (maybe a six-core i5?) since the current dual core Pentium could become problematic, especially when it comes to Jellyfin encoding since the integrated graphics of this thing are crappy, but still enough to be superior to just assigning the encoding to clients which may use Jellyfin apps that do not support local encoding fully or at all. I could always add a graphics card for that if I get my hands on a decent one that I don't need anywhere else.
