I am building my first motherboard, and all the screwholes to go into the motherboard are raised off the base of the case, thus making nothing touch the bottom of the case. but i am clueless on what the science behind short circuits are and idk what im doing, but if i screw my motherboard into the raised screw holes will that short circuit my board since the area to screw it in is touching the metal raised part?
