Anyone have any experience with a NAS running iTunes server and streaming to ATV2? I have a macbook and too big of a library to it on the internal drive. It's also annoying turning on my mac and connecting an external, not moving it, etc. I've been thinking about buying a cheap computer to use as a server and possibly use it to encode movies, but I came across the ZyXEL NAS that has an iTunes server. Anyone used it or something similar?
