We are building a completely new test system for our Sandy Bridge P67 setup. It is comprised of the following components.
Intel Core i5-2500K Processor
MSI P67A-GD55 Motherboard
8GB Patriot Viper Xtreme Division 2 DDR3-1866 Memory
Sapphire Radeon HD 6850 1GB Video Card
Thermaltake Toughpower 1200W power supply
Western Digital 1TB SATA 6GB/s hard drive
ASUS Blu-ray drive
Thermaltake FRIO CPU Cooler
Cooler Master CM 690 II Advanced Case
Starting the install you want to first mount your CPU cooler on your motherboard before you install it into the case. You can also install your memory at this time too. Once you have that completed you can go ahead and mount your motherboard inside of your case.
After that you can install your hard drives and optical drive. This is easily done, especially with the tool-less systems on the Cooler Master CM 690 II Advanced case.
Finally install your power supply and video card. After that just connect everything up and you are good to go.
