Couple pics. Sorry about the quality. First is with stock fans. Second is TY-143 fans. Third is latest w/ duct out back.

I built a caster base to raise case & give easy movement, removed stock grills on bottom & back, modified front intakes to accept 140mm fans w/120mm mounts and use Silverstone magnetic mounting filters for better airflow and quieter performance. No exhaust fans and 3x TY-143 case fans are controlled by PWM signal from CPU_Fan socket on motherboard. Fans idle at 700rpm and normally maximum CPU = 48c@980rpm at about 85-95% load all cores. If I stress it to 98-100% all cores fans speed up to 1050rpm @48c; that's with 22c ambient.
