Having a home built , I suggest , Structured Wiring. The structured wiring can be as elaborate or as Simple as you choose to do. All communications wiring of Any Kind is located at one place. A room that is for this purpose is the way to do it. In the basement is a good place , or on the main floor. Do not put the structured wiring box / panel / connections in the attic , the heat and dust will ruin it. The structured wiring panel can be as simple as a sheet of 1/4 inch or even 1/2 inch ply wood. Something to mount the componets on. You will find business that do structured wiring at Video and Audio places in and around Atlanta. I suggest 'pulling' 2 RG-6 cables to each location , in and out side of the house. You will thank me later for this suggestion. Take a look at these web sites
