wtf is this? I just picked up my motherboard (Biostar TA790GX A2+) and I found something unexpected. I've scanned the manual but i didn't see any mention of it besides in the "box contents" section. I may very well have overlooked it in the manual but I'm at work and I can't spend too much time looking at it right now. Just curious to know if any of you could tell me what it is and if its awesome or useless. It was in the section of the box with all the cables if that helps.
