Amazing quality (it's better than the pictures)

I purchased this case as B grade stock as I do all my cases and it arrived with all accessories still in their packaging and no marks or scratches.

The case actually looks BETTER in person than it does in the pictures, all the different parts are aligned perfectly (which has never been the case with previous cases) and the tempered glass side panel is a huge step up from acrylic. The entire case is modular and can be easily modded or parts added or removed with ease. Case comes with some of BeQuiet!'s best fans.
