I just bought a new house and with it comes new things that I want to do. I have a jailbroken apple tv that has xbmc installed and I have a 1TB HDD filled with movies from my DVD collection. In the past, I would stream from my laptop but I want to get a desktop that is always on that will be used to streak movies and nothing else. (can be Mac or pc) is there anything I need to keep in mind while looking around on craigslist? What is the worst hardware specs that can stream movies? Thanks. Sorry if this has been asked before, I searched but found nothing.
