what is this >?

Of course it could make a difference. Any contact between an active voltage on a motherboard and the metal of the case will fry the motherboard and possibly the P/S. There are different sizes of standoffs to fit different cases and motherboards. Sometimes if a person doesn't use a sufficient number of standoffs, one corner or another of the motherboard can be inadvertently bent toward the case ground causing a short. Even the raised mounds you speak of need standoffs of some type if the surface of the raised mound encrouches upon a surface of the motherboard that has voltage on it.
