I am putting together my own system for the first time, my case is a wood case with sheet metal lining for RF protection. I am now about to mount the motherboard onto the case but I heard some where back that if you don't ground your motherboard or put a rubber washer between the motherboard and the case it could destroy it. I have regular HomeDepot screws and no rubber washer, can I go ahead. Motherboard is a MSI Pro2a and Duron 700, thanks.
