Man, go with either, you CANNOT miss. So decide based on price and looks.
Personally, I own a silver fortress and I can't think of a better looking case, but tastes differ.
Keep in mind that they cool very well on air, but due to their layout installing a water cooling loop may be troublesome. I'm currently water cooling 2 GPUs and the CPU, but this required some minor modding- the HDD bay needs to go if you want some decent rad space. The SSD fits easily on the back of the mobo tray, the HDD... Well, I'm sure it's less than happy with the undignified position it's in now.
All in all, they're both good for air and require some fiddling for liquid.
