This is the same I bought from Fry's Electronics except the one I bought is black anodized.
Remember that you will have to insulate the tracks that runs on the of the PCB on one side.
The trace on one side is ground and the other side is a signal. I used kapton tape.
I wish it would have been shorter and not so high. But it works and looks good.
