Corsair 900D case, bottom screw holes line up, middle line up, top holes are off by a few millimetres.
It has nothing to do with the IO not clicking into place, that is fine, on my case there is a standoff in the center which fits into the center hole of a motherboard, you cannot remove the standoff. You cannot slide the board forward or back once the motherboard sits on the standoff. I was able to angle screw the top holes in gently without damaging the motherboard, I have noticed other people with different cases from other manufactures with similar issues.
My previous mobo was the rog formula x and that was lined up perfectly, so this post serves as a heads up for those thinking of investing in the hero xi...
Cheers
