Papasmurf - I'm considering NAS in the same context as yourself and, despite the earlier replies, I think there are advantages.
My plan is move my music from desktop PC onto a NAS, primarily for ease of sharing, the quiet operation and low-power consumption compared to a PC. The problem with keeping multiple copies of your music, as suggested earlier, is keeping them up-to-date! [...as an aside, of course you should always back-up your valuable collection; using automated backup software to copy to a physically separate drive is a safe/convenient way to do this, safer than RAID and more convenient than manually copying it to here and there]
What I'm concerned about though is the possibility of pauses in the music whilst streaming. Can anyone comment? The NAS will be connected to wireless router, control will be from a media player + Airfoil running on a (wireless) netbook, feeding to an airport express (on onward, digitally, to an AV amp with better DACs than the airport express).
TIA
Andy
Depends entirely on the quality of your wireless network - in theory a 'g' network is absolutely plenty, but in practice it will depend on how robust your network is. I;ve definitely had issues with airport express, which was why I went to Apple TV (though have since gone back to AE for various reasons)
