I have seen working motherboards running while on cardboard, attached to wood, and hanging in the air. Recently I came across a Dell motherboard that had all the screw holes actually labeled as “Grounds”. I’m aware that the proprietary Dell motherboard my be unique and may not apply to the rest of the industry. This did however cause me to think of how the screws attaching a motherboard might sometimes need to be grounded for the motherboard to function properly. This might also apply to PCI card screws and the I/O connectors like the keyboard connector which usually has a little metal flap that looks as though it's meant to maintain contact with the case. This has also made me look at my motherboard and case differently. One of my rack cases is very small and does not have all the screw holes needed for my somewhat large Asus motherboard so part of the board hangs. I have also used and have seen the white plastic snap-in spacers for motherboards which of course would not act as a ground. Half the reason I’m asking this is because I’m building a Mame box and have a motherboard giving me problems that is attached to wood and improper grounds popped into my head.
Has anyone else seen motherboards that REQUIRED the screw holes to be grounded?
