I am about to order my first ATV 2 (with an aTV flash) and wanted to keep my entertainment budget as low as possible. So I was thinking about getting a NAS with only 1 TB. It should stream movies with 780p (1080p) without problems. (Maybe this one: Synology DS110J). I dont know if I need a new router (I have a very basic one) for this. Price should be no more than 300$.
