By the way, in case no one else points it out, the reason so many
designs are done with the fan blowing the air out of the case is that
it is easier to design this way.  Changes to flow paths are easily 
made (at almost any time) by changing the hole patterns in the sheet
metal.  It is also easier to avoid hot spot/stagnant air areas by
pulling the air out of the case.  I have heard about designs that
overheat where the fix was to turn the fan around from pressurizing
the case to sucking on the case.  That may be why only the more
expensive and heavily designed equipment has pressurized cooling.
Takes more engineeing to do it that way.
