What about the Corsair Air 540? Don't know what your budget is but I personally think it looks nice. http://au.pcpartpicker.com/part/corsair-case-air540

I have the phanteks Enthoo pro, and i have to say it is possibly the best case i have ever laid my hands on. It is fully customizable, and for those newer to the game, completly newb friendly. Just have magnetic dishes ready for the screws and maybe a few boxes for the parts you take out such as a drive cage or 2, and the optical drive cages.

All mentioned above are great choices and I am a big fan of the Air 540 as it's so easy to cable manage.

As much as the define S is a good case (I ordered one today) I wouldn't get it unless you plan to watercool as it would look quite empty.
