I was just thinking the exact same thing! xD I did see the pictures, though - very nice. What batteries are you using (that may be a stupid question, but I forget if you've mentioned it)? Doesn't look like you'll have any room unless you expand the case a la zenloc.
I still need to do a little work on the cart slot, making it more stable, adn I gotta fix the video line, other than that, I added a spacer and sealed it up!
