Does my motherboard have a usb3.0 internal header?

Hey community! I posted a question before about if my psu could support my components, and it was answered. Anyways, my case i am looking to buy says it has 2x usb 3.0 on the front panel, but the only way to plug it in is through a usb 3.0 internal header. My mobo has usb 3.0 ports on the back, but i am not sure if it has a port to plug in my case usb 3.0. My case is the Rosewill Challenger U-3 black gaming ATX case, and the mobo is the Gigabyte GA-970A-D3 ATX motherboard. If it does not support the usb 3.0, can you please reccommend a mobo that does and support ddr3 1600 mhz and socket am3+ fx processors. Also can you please keep it around the same price range, if not cheaper? Thank you for all input in advance!!!!
