also, when you're screwing the board into place, get all screws in thier erspective holes but leave the loose enough for the board to move a little. then tighten, starting with the screws closest to the back of the case, working your way towards the front. most people don't realize it, but incorrect mounting can put tensions on the board. as the board heats and cools during use, these tensions can cause hairline fractures, thus rendering the motherboard broken and not repairable.
