Get the aluminum advantage
The Shuttle XPC is housed in an all aluminum case. Aluminum is one of the best metals for computer chassis because it is hard and strong, very light, corrosion resistant, conducts heat and is non magnetic. Aluminum also makes the best looking cases. Aluminum possesses the best strength-to-weight ratio of any metal. Aluminum alloys are harder and stronger than steel. This makes for a very solid chassis that will not warp or twist out of shape after repeated accesses.
