I remember seeing this. You essentially need to cut 2 big holes in the wall in precisely the right locations. One for your recessed mount. And one for the stupid box and whatever else you need to stuff in it. The Snap 21 x 14 box will fit the box fine. The TV has a standard VESA pattern so pick your mount. Some in-wall mounts still do not let the TV sit sight against the wall however. So check those specs.
