i picked up one of those newegg open boxes (crowd grumbles) of a 939dual-sata2 --theres some sort of white powder on the backside that i've never seen before--anybody got any idea what it might be? (never bought a mobo before) I'm going to take my chances with it as i wont be able to return it in the 15day period --I dont have a 939chip yet.-figured it wont be that much of a loss if it doesnt work, as it was only 30bucks--question--what comes with white powder all over it? (answer--a newegg open box--hehe)
