So my motherboard is,

ASRock 970 Extreme3 R2.0 AM3+ AMD 970 SATA 6Gb/s USB 3.0 ATX AMD Motherboard
and case is
NZXT Source 210 Elite ATX Mid Tower Case (White)
The case has 1 usb 2.0 and 1 usb 3.0 in the front. But I dont know if my mobo has USB front headers?
I ordered the parts anyway, im a derp.
