Oh interesting, partner sample of some kind I assume. It's got the July 2012 firmware revision sticker, so I assume it's one of the driver/firmware partner test vehicles that stayed in the labs. I find those cards get heavily abused when their effective lifespan is considered done. They're frequently thrown into big cardboard boxes full of other end-of-life cards and trucked off to be recycled. Thankfully somebody salvaged it from destruction!
Since we're sharing GTX 690s, I got this back in December but forgot to post it here. I think I posted in the new tech purchase thread, though.

An interesting side affect of the GTX 690 being finished before the cooler was, you don't find many proper engineering samples of these cards. They're all production run PCBs and ASICs, but with varying stages of cooler assembly progress. This is one of the raw casting cooler samples mounted to a final board, assembled likely a month or so before launch. This is what the raw metal looks like before the three process alloy plating is applied to give it that awesome silver sheen.
For reference, here's what an early sample GTX 690 looks like circa February 2012 before the decision was made to radically redesign the entire cooling arrangement into what we know and love:

Even at the point of that sample being assembled the PCB was already in mass production.
