|one thing that concerns me about what you did, is that you didn't make it out of pressure treated wood, or even some kind of weather barrier like tyvek or something, what are you going to do if it rains, or gets wet.|
This is a great ideal! How ever it would be cool to use a 3 way switch to be able to reverse the fans. It is real nice to pump out the heat, but in the winter time you might want to pump in cold air from out side. If the outside air is nice and cold it could further lower your case temp and push the warm air into the room. Depends on how hot the air is you might be able to turn out your heater while gaming.
