Installation was very straightforward, first install the motherboard offsets and the I/O shield in the case. Install the optical drive and hard drive.
Install the power supply in the case and set the cables aside. I know that the power supply is overkill, I already had it at hand and decided to use it. Prep the CPU and CPU cooler, apply thermal compound per manufacturer's instructions, install the system memory, and place the motherboard in the case.
Connect SATA cables, power cables, and case header wires. Install the video card. I had tried two, but for some reason the Catalyst drivers didn't recognize the second one for Crossfire. That's ok, I wanted to check out the performance of the Radeon HD 4850 anyway. Connect the power cable to the video card, and that's it.
