Looks like I will be just mounting it Horizontally as that makes my Life a bit easier..
Thinking about buying this:

(I can buy shelves as needed, I also need to keep the girlfriend happy in terms of looks :S)
Putting all of the speakers in it, with room to spare for other stuff, and my receiver.
(Left and Right, Center above the receiver in the Middle)
Will putting it lower than the screen really affect sound that much? I am thinking I can angle the Speakers to Point towards listening height. Other option is to put speaker stands next to the tv (But there is minimal extra space, ~.5" on each side my tv measures 54" wide.)
