You might want to go for z77 as opposed to z68, it has more features (eg. Lucid Virtu) and adds little cost to your system.
For the Corsair 600t, there won't be any problems with that, it all comes down to personal preference with cases, I personally love the 600t, its full of good features and looks great.
