How to Create a Recessed Audio/Video Pier for a Wall Mounted TV

The only good place for the TV was on the wall above the fireplace which has a awkward shape.
The problem was where I'm going to put the components Receiver, Cable Box, Blu Ray Player, etc.
A regular Audio Pier would obstruct the fireplace.
The solution: a recessed Audio/Video Pier/ Shelves for all my TV components.
The first  picture is AFTER and the second picture is BEFORE.

The fireplace needs new surround and hearth, but that is going to be another Instructable:)))

This project was inspired from the member SantaB Instructable:http://www.instructables.com/id/How-To-Create-Recessed-Shelving/ .
Many thanks to SantaB for his well done Instructable.

Step 1 Check the location where the A/V Pier is going to be be installed.

The wall is deep, so I decide to build it 16" deep by 21" wide by 60" high.
With a Drywall Saw cut a hole and  check for obstructions, pipes, etc in the wall.
I had a stud in the middle which was not a load bearing one, and the power outlet and the coaxial cable could be easily relocated.
The only problem was a gas pipe for the fireplace which was moved by a Licensed Plumber in less than an hour.
