Icybox IB-866-B USB 3.0 Adapter front with 4 port bay 3.5 '' Black (Accessory)
2 USB 3.0 ports to connect internally and 2 usb 3.0 ports to connect two external ports. No problem, everything works to perfection itself whether to bring out the cable to plug in the back, 2 external ports. I associated with "PEXUSB3S2E2I StarTech.
