Nice looking rig. Though, I'm fairly certain that the heatsink fan is pointed the wrong way. Generally, it should be expelling the air towards the back, where the fan on the back will help pull it out and cool the system better. Not sure why they'd have it attached the way that it is. That heatsink looks alot like the one I had in my old system (looks like a Zalman CNPS9700 or so), and it was supposed to be pointed differently than yours is. If you have any issues with heat, I'd say that's your issue.
