Where on earth does this go?

It's useful for whatever you need it for. Like a legacy CD-ROM/DVD or HDD. Two of them can be used with a cheap cable adapter to give an additional 6 or 8 pin GPU connector (assuming your PSU doesn't have enough dedicated ones).

Thanks man, I had no idea what it was or why I have one. Cheers for clearing it up!
