Warning this requires modifying the cables of the power supply. If you don't have knowledge with such things don't attempt this or do, I can't stop you.

I found that all cables were supplying 12v except for the power on signal cables, they were using 5v. I also installed a 100ohm resistor to the 12v 40mm fan, so it wasn't running at full rpm to prolog its life.  

the lid requires 2 5mm screw no inserts.
