I am a first time builder and I am concerned that the motherboards edge is touching the back of the case( wher the cables go). I dont believe it should be but it has to in order for the connecters to fit into the face plate. Can the motherboards edge be touching the case?
The plastic of the motherboard is not conductive so it should not specifically be a problem, unless an metallic parts are touching. The stand offs (where the motherboard mounts to the case) should set the motherboard in a very specific place. As long as the motherboard is secure on the stand offs, it should be no problem.
