As gamers, this is probably the best thing we've ever seen. An amateur woodworker converted a standard cabinet into the ultimate gamer's cabinet through some hard work and some wood. Each level holds a game console, elevated for maximum ventilation. He also drilled holes on the sides to put lighted PC fans to help move air.
An added bonus, the sides have hooks and holders so he can keep his controllers neat, but still in view. This mod requires some woodworking experience, but you should be able to take this idea and run with it to come up with an easier solution. Sure beats our current "put everything on the floor" approach.
