Your only suppose to drill 4 holes otherwise dust and other junk can get in to easily. 2 holes on each of the shorter sides. Then for added cooling you can run a fan on the side blowing threw the holes. Make sure you run a screen over the fan and the other 2 holes to make sure that the dust that will get into the MM is at a minimal. Happywing here on rcm uses this mod alot on his MM's.
