thanks for the reply DOH! Typo, I meant X42. I also forgot to mention on pcpartpicker it told me it's not compatible, but it also said it was unable to verify. I don't see any reason it won't fit, but I've built so many computers in the past where I just assumed a part would fit, and it wound up bitting me in the butt lol. So I thought I better make sure before I spend money.
