Forced air cooling on the systems I currently have produce a tempurate rise 
f
about 15 degrees above ambient. In a 75 degree room, that means the exhaust 
air is 90 degrees. How much hotter do you think the internal componants are 
going to run, if you stop using forced air? Quite a bit!

People who know what they are doing, and aren't constantly moving things 
around (also not good), don't need constant access to the internals of the
machine they are using. They also reconize the protection the case provides 
for those internal components.
