I really like the Bitfenix Prodigy still. I have an empty one sitting in my bedroom, I haven't brought myself to sell it because I keep telling myself I'll use it again. Even though it's been empty over a year now.
I like the build quality and the aesthetics. It still impresses me how nice of a case it is now, as it did when it was first released.
I very much enjoy most of CaseLabs cases. The SMA8 is my favorite among them because it offers great compatibility for water cooling, great looks, features of a list that goes on and on that you can get for it if you so desire, different tops, sides, inverted mobo trays, etc.
So, Far I like to work with the NZXT H230. It is a great modding case to those who want a bit of a challenge but not for reasons you may think. Anyway, for it's price, it works well for what I want.
Danger Den all the way. I have several and I will never sell them. I do like the MountainMods UFO which was a pleasure to build in. Can not go wrong with Caselabs too.
Corsair Air 540. It makes cable management easy as pie, and it has tons of room for water cooling. The Fractal Design Define R5 is my second favorite case. It's sleek and silent yet loaded with useful features. It's madness.
