As easy as they are to crush, I also have to give some love to the GBA boxes. The bright colorful artwork on them just looks so good, and I love finding a pristine box for the shelf. Reminds me of a nostalgic days, and it's nice to know that someone took care of that item for all those years.
Otherwise, I do love seeing the spots for memory cards or GBA carts in the PS2 and DS cases.
