That is a very nice collection you have there. You have it laid out very well and it is very organized. You also have a nice huge queen alien in there and I can;t help but love the Alt/BT's you have in the lower left!
I have seen these cases before, someone posted their collection over at Seibertron and they had their TF collection in them. They display the figures so nicely and I would love to have about 5 cases to put all of my stuff. Alas I have really no room for display casses and so the top of my TV, Book shelf, and Computer desk act as my display for my Macross and select TF's.
