All those parts will work great together.
The only part I would change would be the power supply, while the one you picked isn't a bad unit by any means, it's fairly low end as far as Corsair go, and you won't need anywhere near 750w. I'd recommend something like this:

You can safely ignore what Geek-9pm said about the warranty, you are correct that all components come with their own warranties, you don't need to buy anything else.
Have you thought about buying some kind of warranty?
With a high-end home build like this, you have to pay extra for warranty .
Not true, as said above, all parts come with warranties, you do not need to pay anything extra! If you had actually read the thread that you linked you would have found that it does not mention paying extra for warranties, it refers to registering your purchase with the manufacturer of the component which, in some cases, is required to get warranty service.
