From the HardOCP article, "Can you imagine a video card without any flimsy plastic parts? Now you can because the NVIDIA GeForce GTX 690 will not be composed of any cheap plastics. A heavy duty dual vapor chamber cooling system relying on heavily nickel plated finstacks will sweat what little heat these GPUs pump out. A cast aluminum frame with trivalent chromium plating gives the card a unique look and tremendous rigidity. An injection molded magnesium fan housing adds to the formidable stiffness of the card. A brand new thixomolding process was used to get the required part precision."
