First off, thanks for the access man!
As someone who doesn't know excrement about the inner workings of plex beyond being able to login to it, how do you get all these movies/shows? Pretty awesome.
I have three servers that I run. One that actually hosts Plex and two that run Radarr and Sonarr respectively.
Radarr will search for movies & Sonarr searches for TV shows. They use NZBs, which are old usenet files from early internet days. You add the movie or show and it'll search the hosts I subscribe to on a regular interval. It's a paid subscription but still way cheaper than cable.
I have two NAS servers that add up to around 34TB of storage. I started doing this for myself years ago, then started sharing with family and friends. I would do this regardless so figured I'd share it with you assholes, I've had known some of you longer than I've had kids....
