If you don't know what these things are:
Sickbeard is a web app that keeps track of your TV shows/movies/anime that you have downloaded
SABnzbd is a client, similar to utorrent/transmission, but instead of doing torrent files it does nzb files
sickbeard can be configured to cue sabnzbd to download the newest episode of a tv show once it is uploaded to the servers. it acts like your DVR, but without any of the tv box nonsense
I used to have a really sweet setup with all this + xbmc to play all my tv shows, but shut it all down when I moved and built a new computer.
I figured I'd get back to it and get it up and running again, instead of manually downloading or streaming shows in <1080 like I have been the last year or so.
