This has been such a great topic and you people are really helping me out here, thanks for that.
As I said, I constantly keep on changing my mind, and so I am this time. Right now the LCD in front in 51% winning. I was just checking one out and when blanked, it blends into the wall quite well. Besides, it was my original choice, anyway.
But what puts me off with the side mounted option is the extra furniture needed, I'd like to keep the upcoming room really simple. If I ever changed my mind, getting rid of a big TV is probably easier than with a $700 Sound Anchor.
Related to the topic, I'm wrapping up my plans for my new desk. Quite like a Sterling Modular Plan A, but with 13 units, no low front racks, foot space under the console and just 2x 4U space on the back for PSU's and such.
