A little expensive but practical
I recycled an "old" CM Asus M3A78, AM2 processor and DDR2 in a living room box (Silverstone) in order to watch Netflix and Youtube on the TV. As this box has USB3 connectors on the front and the CM only has USB2 connectors, I needed an adapter to take advantage of the front connectors of the box to plug the USB key of my wireless keyboard/mouse.
This adapter is perfect, and the length is sufficient to reach the different slots on my motherboard. Nevertheless, I give it 8 out of 10 because the price is a bit high for such a basic adapter.
