I have a Zalman Z9+ , and it is a great case. There is a lot of room for cable management, and the supplied fans keep everything nice and cool, while running very quietly. The Z11 chassis looks the same as the Z9, with different sides, top and front bezel. On Newegg the description for both says Spacious Interior for Installing 290mm Card
You cant go wrong with either one. They are definately quality cases. As far as the Z11 being ugly..well thats an opinion, and you know what they say..Opinions are like a**holes, everybody has one. If you like it get it.
