This idea would be perfect because of the fact that MMA and the UFC are so popular right now.
The idea pretty much presents itself because it's quite a simple idea. The components would all be housed within a mock build of the UFC or any other MMA organization's octagon ring. This idea is also great because layers of steel mesh could be used as the outer area to provide basic rigidity while maintaining a decent level of airflow. The main fighting area could become a mousing area which would be layered with mousepad cloth material. The netting could be removed or pulled out of the way to access the mousing area. The optical drive would be stealthed as one of the sides of the bottom of the octagon which would simple slide out upon a button press. Another side would act as the I/O panel.
