Which case should I choose?

Which one do you prefer?

That's your answer.

EDIT; Personally id choose the ZALMAN, I think it looks a little nicer  

it depends on your preferences

I bought the Zalman Z9+ case last month, and it is a great case. There is a lot of room, space for cable management, and best of all it runs very cool and quiet. The fans that come with the case make barely any noise. I would recommend the + version because it comes with 4 fans instead of 2, and a fan controller with temp gauge. I was definately impressed with the quality of the case.

Ok, I'll take that into account.
