This key is good for a motherboard with no sound card. As for me I have added to a server and it works perfectly. Only flat and of course the weight and size of the key. Indeed even if it is more than reasonable one should not forget that the cables are connected to it which weighed down tremendously. Knowing that tt ca fit on a USB connection or you'll end up with a broken jack with either twisted usb port. But if you buy a small usb extension cable to which you will connect this one, the everything will be OK. I would even say it's mandatory if you do not want to burn this one. As for me is what I've done and everything is for the best since I added the extension. So to recommend.
