The thread that won't die!!!!
Gaming pc's aren't green, especially overclocked ones. They're the SUV's of the computing world. They use rare materials dug up in some of the most hellish places in the world, the components are put together in sweat shops in the Far East where the workers recieve extremely low pay and conditions, then they are shipped half way round the world on enormously polluting cargo ships. After you've assembled the components the PC draws a large amount of power mainly generated from fossil fuels, then when you overclock it, it uses considerably more. What's more it'll be obsolete in a few years and all the parts will end up in landfill.
Your 'Green Dragon' may or may not be more green than my rig, but I am not deluding myself that building a gaming PC is an ecologically sound thing to do. I have one because I want one and can afford one and choose to accept the environmental impact.
Choosing components the way you have is like buying a Porsche Cayenne rather than a Range Rover because Porsche have a bit on their website that says how much they like trees (I don't know if they do!). If you really cared you'd have a VW Polo Bluemotion, or to extend the analogy back to computer games, an Xbox.
