At the moment my iMac has become a glorified iTunes server, so I'm considering selling it and buying an ACD for my Macbook Pro. However, I'd like to have an iTunes server running on the network regardless of whether my Macbook Pro is switched on, so it can serve the other computers here and the ATV. So, does anyone know of a NAS which is (reliable obviously) capable of working as an iTunes server on its own? Ideally with mirroring capability so that I don't have to worry too much about a drive failing. Any ideas? I'm not having much luck with the search function so far. Thanks, Mike.
