What do you mean by bringing the duct closer?
You made a good choice--this motherboard/CPU pairing has been great to me so far. That sounds like an awesome gig that your brother has. I am tangling with similar issues on a much smaller scale--another project of mine is trying to make an RC car go as fast as possible (I strapped my phone, with its GPS, into the car so that I can have a good speedometer). If you would connect me up to him (james.wattsa@gmail.com), I would love to ask him some questions.
