The Magic-3D is constructed of steel but the case is light enough that it would pass for aluminum, I think part of that is because the case makes use of mesh in two major areas, that being the side-panel and the front bezel.  The other thing that is slightly different about the Magic3D is the use of a one piece bezel, it is so common to see doors that open that cover the top half of the case only, here the entire bezel is hinged to open which makes it rather unique.

Even though the entire front bezel is covered with mesh the only part of the mesh that is functional is the lower 25%, this is where double-bladed turbine fan is located.  The bezel/door goes on to cover the four 5-1/4" and two - 3-1/2" drive bays along with the power and reset switch and power LED and activity LED.

To break the monotony of a single color bezel Aerocool has backlit bezel on the Magic-3D so that it rotates red - blue - green giving you a soft light that really is not that distracting when lit.
 

Along the right edge of the case you have access to all of the accessories for your system, one - FireWire, two USB 2.0, Headphone and Microphone connection points.

Looking at the mesh used on the side panel of the Magic-3D you see the outline of the 120mm fan that has been fitted into the panel using Aerocool's O-Ring design adapter.  When you can combine a total of three 120mm fan into the Magic3D there is no doubt that this case will be well ventilated and should be an ideal candidate for  being used as a case to overclock in.
