I drill tapped 4 standoff screws into a metal board. Then i layed the mobo on top and screwed 4 screws into the standoff screws. There is about 3-4mm clearance from the metal board to the mobo. Nothing is touching besides the screws on the board. I used the small screws so that the head of the screw is touching nothing besides the area it is supposed to sit on.
Am i doing anything wrong? I feel so afraid to get a new board then to have it fry again.
