i am getting a case that has 2 usb3.0 in the front panel and it has a 20 pin connector that goes to the motherboard. my motherboard does not have the onboard 3.0 but does have the rear panel usb 3.0 slot. I am jsut curious what my options are. I would be fine with configuring it so they function just like usb 2.0. So is the best solution some sort of adapter cable? a pci adapter? I do not know much about USB3.0
