Actually, about that noise problem:
Turns out, I only get the noise when i plug my headphones into the convenience headphone jack on the front of my Cosmos case. If I plug into the actualy gigabyte motherboard, the sound is crispt quiet. Very nice. So, the problem is cooler master, I guess. it's ok, once I install the big knob, I won't be plugging any headphones into the case.
