Have you seen this before?
I'm looking into getting a raspberry pi and getting a setup like the one in the link when I move to my new apartment, and this seems like a great alternative to sickbeard/couchpotato since you don't need any subscriptions.
tried it before, it is very slow when you get a high bitrate 1080p movie going but the dvdrips/bdrips play fine.
sickbeard and couchpotato are just the software, raspberry pi is the hardware that can run it all. you don't need a subscription for them.
but to get all your movies and tv shows and to make it all seamless and easy you have to sub to a usenet provider and usenet is a whole nother ball game! you can use torrents too but i would not suggest it!
