Old school eh? I haven't used those in a long time. qBittorrent has search built into it, but search is better with the 'arrs. Jellyseerr and the 'arrs make searching torrents as easy as browsing movies in a streaming service. Search and browse movies in Jellyseeer. Read about them, watch the trailer. Then click "Request" when you find a movie you want to watch. The 'arrs then automatically find the torrent, and download it using qBittorent, or one of those other programs you mentioned.

I was just playing with my setup and learned that Usenet gets slow AF if you download to an NFS share. Back to downloading to local NVMe then copy the finished off to the server. Also at 90% full thrashing becomes a real problem. More drives on the way. I need to add jellyseer too.
