I used the corsair carbide 500r on my recent build and loved it. 600t looks more of the same greatness.
Here is a picture of my finished build... very easy to work with, very spacious, and great cablemanagment. Was my first build ever, too.
you'll probably even be able to get it even neater since you have modular.
One note of advice I can give you; you might want to get low profile vengeance ram. since you will be filling all four slots. I have an aftermarket cooler like that, and on my Z68 by msi I would not be able to fit the ram that big under the heatsink in the 4th slot.
