Actually, if you did pipe the air into the computer through a small duct system, you could probably control where and what its blowing on, and also an custom designed exahust system.....And it might be noisier, and add to the cost of each unit!! I can see them welding pipes together into a manifold... Whenever we put Air Handlers into houses, by biggest beef was the noise, they only had one Cold Air Return somewhere in a central location....with exhausts (vents) around the outside wall of the house...If your so damn worried about dust in your computer, call your local HVAC contractor and have an electronic air cleaner or those huge filters (Spaceguard?) installed in your heating/cooling system. They do work well...And you got a choice of many American made products from Honeywell, Trion and United Technologies (UT's brand names are Carrier, Bryant, Day and Night, Payne)... -- C-UseNet V0.42e Ronald Kushner Life in Hell BBS +1 (313) 939-6666 P.O.
