The motherboard standoff key in my nzxt phantom 410 case has me putting the standoffs in places that don't line up with my asrock 970 extreme3 board. I'm looking at the atx key, maybe I need to use the flex atx key? Is there anyone else who has had this problem?

Flex ATX??? Never heard of it... Keep the board above the case and screw in the right standoffs... As simple as that...
