I have always wondered that also.  The engineers know that heat rises, 
thus vent the top of the case.  duh???

Years ago, CPU's didn't get near as hot as what they do now and most 
people only had the computer on for a couple of hours at a time when 
they are using them.  Customers also use the top of the pc to put their 
glass of ice tea or whatever favorite beverage of choice is, and some 
would accidentially spill into the vents or fans in the top of the case 
if they had them.  Others put their scanner or external zip drive, ditto 
drive or CD-RW on top of the pc so that it doesn't clutter up their 
desktop.  A scanner on to of the pc isn't a steady enough surface and 
tends to make the scanned image too fuzzy, but it is an interesting 
effect if that is what you like.
