Incredible pictures of the build. Love all that custom stuff on the walls and the ceiling is ridiculously cool.

Sorry to hear the final pieces aren't coming together as smoothly as one would hope. That said, the room seems like a big enough investment that your brother should take his time (and it looks like a little bit money, unfortunately) to get it right.

Post some more pics of the final set up with speakers, etc. I really want to see it in its completed state.
