Your case which seems to be exclusive to Ebuyer is more than big enough for your motherboard as it is suitable for ATX Motherboards and comes with a 650W Coolermaster PSU
The motherboard is way over the top and more of a specialist board,its for people who take overclocking very seriously and also it supports Crossfire and unless you are going to put in a second GPU then there is really no point in the board. and by the way no such thing as future proof as far as computing is concerned.
your graphics card is fine and will play the games you mention fine.
Your PSU as I said is more than enough. I would change the single 1TB hard-drive to 2 500Gb hard-drives as 1 drive can backup the other then if your main one fails you haven't lost everything, but that's a personal thing.Unless you are going to buy the 64Bit version of Windows 7 then there is little point in 8GB of RAM as Windows 32Bit will only see a maximum of 3 and a half GB of ram. You really do not need a Freezer pro cooler unless you intend to overclock your set up. The cooler that comes with the chip is more than adequate for your needs. Nice fans by the way, I have a couple of blue ones myself. It looks like you have a large budget for your build and whereas there is nothing wrong with what you have chosen you could certainly improve your selection. What is your budget by the way?
