I messed up a little when mounting the motherboard on the standoffs. It works but I used different screws like the one you would use to hold the gpu in place for the mobo should I remove them and add the right one. When you try to remove it the standoffs unscrew too. If I am to use a nut or plier to hold the standoffs from the back and unscrew it from the front then u can remove it but should I.
