A good case in my opinion is the Fractal Design R-series, the most recent being the R4.. I have had the R2 and was really happy about that, good cooling, very silent and good cable routing options. And I would imagine that the R4 is even better in every aspect and there is a version with a nice wondow..
but the corsair 600t is also a good choice if you like the look and if you want to spend a little more on the case.
If you want a really big case, then the upcoming Corsair 900D will probably be really good too, especially if you are thinking about doing a custom watercooling loop in the future.
As for tips on cable routing, just do it as simple as possible and get as many cables routed to the back of the motherboard-tray! :)
