The case came with a lot of extra screws in a Zalman plastic bag, but no standoffs. I seem to be having trouble as there are no screws for the motherboard to screw into the standoffs. I'll contact ASRock about that.
Also, when i lay down the motherboard where i have located the standoffs, there does not seem to be much space between the motherboard and the motherboard tray. It is a couple of mm space, is this normal?
