Fractal Design tries to please its users, both current and future ones, by means of the possibility of buying several pieces of the Fractal Design Define R6 separately. This box has dimensions of 543 x 233 x 465 mm with the legs that form the base of the same, and reaches a empty weight of 12.4 Kg. With said dimensions, it is capable of housing base plates of format up to E-ATX, it maintains 7 + 2 PCIe expansion slots. Ventilation, the Define R6 has numerous positions for fans, up to 3 frontals of 12 cm or 2 of 14 cm, up to 3 superiors of 14 cm, two inferiors of 12 or 14 cm and a rear of up to 14 cm, maintaining filters of dust in all air intakes. It is also compatible with radiators for RL in the same configurations as the fans. What Fractal Design adds today is the possibility of customizing this box by purchasing numerous modules that will be sold separately from it, or as a custom configuration in your purchase. In this way, up to 16 different versions of the Fractal Design Define R6 are available for purchase. Among these versions you can choose the incorporation of USB-C 3.1 Gen2 ports, 9 fans with a serial hub to manage them, open top configuration to support 420 mm top triple radiators or the possibility of incorporating tempered glass on both sides. If you already own the Define R6, Fractal Design enables you to purchase modules in which you are interested so that you can add them to the box on your own. This strategy reminds us of Cooler Master, who tried to offer modules for their Maker boxes without much success We will see if Fractal Design manages to take off this type of strategy in its boxes.
