"The theory behind this project was that I could use a system of pipes and fans, to suck freezing cold Pittsburgh winter air from outside my room and blow it into my case. Ideally, the pipes would be made of thick PVC so they would be good insulators and keep the air cold until it reaches the case. Also it would have been nice to have had silicone rubber seals between each section of pipe and around the fans that pump the air."

Right we understand. That's what makes us  "geeks" cool; we make paper cooled computers. The project is here, if you want to make one :)
