The DRX exhaust ports
All the best engines have dual exhaust ports, and the DRX's twin graphics cards each have theirs. The intel Core 2 Duo CPU breathes thru its own as well. It takes a surprising amount of air to cool these components, and no one ever suspected them to all fit in one laptop. These beautifully designed exhausts vent the heat straight out the back to keep these amazingly fast components cool.
