You may want to reconsider that statement after the first fan failure in 
your mini.  We've had quite a few Mac's in the tv station, as video 
servers, graphics composers, etc.  The airflow for cooling in them is 
controlled by baffles to get the maximum air flow past the hot spots, but 
a fan failure usually cooks the whole thing.  And at that time, Macs 
warranty did not cover collateral damage from a fan failure. Cooked cpu? 
Too bad, so sad.
