I currently don’t require much transcoding but I imagine I will as time goes on. I would rather not have to police the filetypes for downloads as heavily. That being said, It will be an always on server so power is a consideration. I haven’t thought about how expensive it would be to run a tower server vs raspberry Pi.
Check the compatibility with Linux but I also used Ubuntu with very little problem. It works flawlessly for me. I had no experience with Linux before this and was able to set it up with some googling and Asking ChatGPT for some useful commands. It was a fun project. The *arr suite is great.
