I'm fairly new to all of this and have just purchased a Hitachi 42PD5200 plasma. To keep things tidy I had intended to mount the plasma on its flat wall bracket attached to the existing external wall and then construct a false wall over the top; so effectively the screen is flush with the cut out in the surface of the false wall. I can then all cables behind this false wall to the assorted components. My concern is that there is sufficient space for air circulation behind the false wall - which I intend to construct out of MDF. Does anyone else have any experience of doing anything like this? Glad of any help.
