We need to place the motherboard onto 4 standoffs to tighten it and often we will carelessly scratch it when we try to match the fastener hole on board with the standoffs. Is there any fool proof way to avoid it. I know it is common sense to just be careful while carry out this process but I wish to understand more about the fool proof method. Thank you in advanced.
