I don't know what I'm doing with this build

Oh okay, That's what I originally though.
What does the heat sink for this motherboard look like and how do I recognize DDR3 ram is the stickers have been removed. Those are some of my last obstacles.

Measure:


And measure (mechanical drawings are on pg 51): http://download.intel.com/design/processor/designex/320837.pdf

Holes should make a 80mm square per the drawing.

On the RAM sticks read the model number, PC2 means DDR2 PC3 means DDR3.
And the memory of the graphics card has nothing to do with your RAM, you can install the crappiest PCIe card that has DDR1 RAM on a DDR3 system.

The original cpu cooling fan is a self contained liquid unit, most powerful fan iv ever seen. A liquid unit is the only thing that can keep up with the heat of this computer, this board puts a lot of extra power through the processor. It runs same wattage through the processor no matter the actual needs of it
