My MCE computer is attached to the TV via a 35ft DVI and optical cables. The DVD is a USB device that goes in the A/V cabnet that is in the same room as the TV, but in a different area. Long cables under the house are a nice low tech solution to keep the PC out of the way. The fireplace, however, in the winter time is where I like to sit when watching TV and its fan generates its share of noise.
