I have the coolermaster haf 912 and I know where the stand offs go but I don't know HOW to put them in. I'm sure a normal screw driver won't work so I tried screwing them in. It worked but I can unscrew them easily. Is that ok. Also the case came with two stand offs per installed they look differant then the ones that came in the Baggie but are the same color, I hope that's fine.
