Do you have internal usb 3 ports, header? Where do you want to connect it to?
internal usb connectors look like these, you can see the cables on the akasa one you linked.
If you have a port inside, all of these things just a plastic box and some wires inside. Choose the cheapest one, or the one looks nice. If you don't have a port, the interesting part is the pcie-usb3 extension card
