As I said before the air circulation/cooling is the most important thing to me because I will be overclocking. Second is noise levels but I really don't care too much about that.
Like I said earlier, check out the Fractal Design R4.
The 140mm fans are whisper quiet. The only downside is they don't sell them separately.
Cases are such a personal thing. You have 2 people that really like the 410 while I think it looks ugly. The great thing is there are so many cases with so many features to fit everyone.
