I got a haf 912 case and an ASRock Z77 Extreme4 ATX LGA1155 Motherboard but it says, "ASRock Z77 Extreme4 ATX LGA1155 Motherboard has an onboard USB 3.0 header, but the Cooler Master HAF 912 ATX Mid Tower Case does not have front panel USB 3.0 ports." Will it still work since I have seen many people's builds with those parts.
