Jean-Max I will look into that, although I am not certain what the advantages would be.
I have my media machine in the closet and is wired into my home audio and television and generally runs headless.
I control it remotely, presently using Messiahs' "xpTunes - enhanced remote server (alpha)" plugin
http://yabb.jriver.com/interact/index.php?topic=43402.0, wireless keyboard & mouse, (soon to have) RF Remote, as well as a laptop with VNC.
In this fashion I cannot hear the PC's fans (noise problems eliminated on-the-cheap) and I have Zones controlled by MC as well as selector switches where local sources also exist (main listening area).
My Main point being that I am using
local hard drives eliminating network slow-downs and additional hardware. I also have a direct interface between the motherboard and the hard drives, eliminating numerous other possible corruption opportunities (file system conversions with NAS, additional read/write control devices, etc).
Modern motherboards can handle quite a number of drives (I see boards with 6 SATA ports plus IDE) and 750gb drives are reasonably priced since the 1tb drives are appearing more.
Add a good case and it can easily handle 3 to 5tb.
So, is there really an advantage to the networked storage approach?
Unless your goal is to be all wireless perhaps?
