Tribert's Profile

I suggest moving all your components next to the TV, and stand them up like books. Then wrap the components with gutted out books, or hide them in decorative boxes just remember to make cut outs for heat ventilations and the IR. Then run all the wires along the back wall and down to outlet.
Or you can relocate all those components inside the cubby hole, mount curtains to hide the cables running up to the tv and cable.
