I can't get the last set of screws out. You know the really tiny ones, holding the metal plate to the motherboard. Does anyone know where i can get a screwdriver small enough for these screws. I don't want to spend more than 5 bucks or at the most 10 bucks.. I know that they sell some at The Source (Radioshack), but don't know which one to get. Can someone give me a model #. Thanks.
