It is also a good idea to use cable clamps to hold down and guide the cable inside the enclosure.

4 Self-Adhesive rubber pads stuck on the bottom of your enclosure are a good way to stop it from sliding around when you are playing a game. These can be picked up from most hardware stores and are pretty inexpensive:
