I've built several systems in the past and by following the norm simply put the screws through the motherboard and into the back pegs. Looking at the holes in the motherboard I see a bit of metal around each hole. It's not really solid, but it's there. The whole case is metal, so I couldn't help but wonder if by grounding the mother board to the case it could cause minor problems sometimes. I've also heard of a rare person here and there having a weird problem where their system won't start with the board in the case. But it may not have been related to the screws and holes, but a power supply incompatibility instead from what I remember.
At the same time I figure most people just screw down the board and it works fine as it does for me. But looking in the pile of screws I got with my Antec 900 case, they give me like 7 or 8 little paper washers, which then make me wonder if I should use those, LOL. So I turn to my asus motherboard manual which simply says to screw down the board. And for all I know, Asus WANTS the board to be grounded to the case with the screws for some important reason. So by putting washers I could be defeating what they wanted. Does anyone know if it even makes a difference?
Here is a picture of an Asus board. It shows the hole and the metal around the hole in a pattern like most boards have. There is no screw in it, but you can see the threads behind it.
