I have the coolermaster cosmos-s, my system is 4 yr old and build quality is excellent. I do not, however, believe that it is any superior in quality to other cases at a cheaper price point. I wouldn't now say that the cosmos is a great looker, at the time i found it aesthetically pleasing but would now rather have something as minimalist and unobtrusive as possible. Can't say i would pay £100 for that luxury, as nice as the silverstone looks. I would rather spend the saved money on the hardware or the screen which is what i look at when i use my pc.
