The cable length, which was my main concern turned out to be just perfect. It fitted perfectly in my chassis and across the motherboard. I would not recommend this if you're using a very large board, like a server Xeon board.Installed it almost as it arrived, plugged in a couple 4TB external drives and works perfectly. It's just been days since I started using it, so this is more of an early verdict. It works, and very well.
