The MusicXPC is housed in an all aluminum case. Aluminum is one of the best metals for computer chassis for a few basic reasons:

Hard and Strong

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.

Very light

Aluminum is extremely light and therefore the MusicXPC Professional's chassis is very light. The MusicXPC Professional is light enough and small enough to be call a portable desktop. This is one computer that invites you to take it to the rehearsal because it's really not a hassle to move it around - and the strain on your shoulders would be minimal.

Corrosion resistant

Because of its tendency to form a protective oxide coating upon exposure to the atmosphere, aluminum needs no further treatment in ordinary environments. This means that the chassis inside and out will tend not to corrode, rust or discolor. This makes for an extremely durable computer that will last many years and remain in pristine condition if cared.

Thermal conductivity

Aluminum is 4 times better at conducting heat than steel. This means that when your machine begins to run hot during extended constant-use periods, the chassis itself acts like a giant heat sink and helps to drive heat to the outside of the computer.

Non-Magnetic

Aluminum is the preferred metal in applications where magnetism may be a problem. In a studio with powered speakers and computer CRT monitors in a small space the MusicXPC Professional is the perfect computer for minimizing magnetic interference.
