Fractal Design made a great impression on us last year with the debut of the Define R3 ATX chassis and its smaller sibling, the Define Mini Micro-ATX chassis. It is hard not to love a high-quality, well-built, sleek and unobtrusive chassis and these are all qualities the Define series of chassis exhibited to us. Not content to rest on its laurels, Fractal Design went back to the drawing board to come up with several enhancements to the design of the R3 with the new Define R4 ATX chassis. The main refinements offered by the Define R4 are larger and improved fans, a more flexible hard disk drive (HDD) cage, a wider case body for easier cable routing, additional mounting options for 2.5 SSDs, a new tool-less front fan holder, support for liquid cooling radiators, a new fan controller that is integrated with the front panel, and an additional USB 3.0 front panel port. *"
