Great post! I would think the stock power supply would be a bit strained by all those fans. You may want to do an ATX mod, or perhaps add a second mini supply just to power the fans. Sounds like you have a good handle on things. Take advantage of the experiance and advice here at Macmod, some of these guys are truly artist when it comes to modding and over-clocking.
