+1 - if you can weld the square tubing into a continuous loop or back and forth pattern you can use a "side-venting" fan (possibly called a scroll fan??) to push air through the entire structure and keep it cool. You can effectively cool the entire unit with one fan (unless you have a 6 foot tank )
