How to clean the new Mac Pro?

Personally I adopt this method: I remove the protective cylinder, and insert a small plastic insert into the upper fan which prevents the fan from turning and getting damaged. (It must not turn by the compressed air; the circuit would fail). Then I blow the whole Mac with the compressor starting from the sides and going down, still blowing from the bottom upwards. Then I also pass internally to the cylinder, especially in the upper part where there is the upper curvature. In case the dust does not go away, I use a very soft, clean cloth. The air must obviously be as dry as possible and free from dirt. If you need to pass a soft brush in the most internal and not reachable points.
