as far as the comp noise - theres several ways to have a dead quiet pc, including keeping it in another room, having a fanless soution (some mini IPX simpleton to run the media front of the system) and lotsa ways of making your pc quiet (passive cooling, quiet fans, water cooling, quiet case, or noise killing enclosure for the machine), if it has to be close to the stereo.
