A lot of our customers prefer that there wires be hidden so I usually use a rack like a bellogetti that has a wire run down the back of it that hides the wires. anything going into the wall I use work boxes with the proper face plates and if they don;t make one for the interconnect I am using then I make one out of a blank plate and a dremel. Also if you go the blank plate dremel approach you can put several cables into one wall plate.
