When it comes to cases there are two different types. The first is the flashy cases that are meant to grab everyones attention and show off all the cool hardware inside. The second is the sleek professional looking case that is all about style and function. When it comes to Fractal Design I always seem to place them in this second category. They don’t make anything flashy or over the top, but their cases are always functional, cool, spacious, and what I like to call business sexy. Their Define cases have always been a perfect example of this, today we are going to take a look at the Define R4, their lastest version.
