I had a heat issue as well. My front is open but the back was closed. I cut 2 (80mm) holes in the back of my stand. Went to radio shack and picked up a power suply and 2 case fans. While gaming I run the fans at 12v while watching Blu-rays I run them at 7.5v.
P.S. you can find these materials on-line for cheaper, but when I want to do something I want to do it now so I'll spend the extra $20 and by reatil.
