Fractal Design Define C Black Solid Mid Tower Cabinet
So many cases on the market today are made to be all things to all people. However, for many this results in a chassis full of empty bays, unused mounts and excess bulk. Created for those who demand a flexible platform for a powerful Micro ATX build that wastes no space, the Define Mini C is the perfect solution to satisfy this balance of capacity and efficiency.
Smaller than the usual Micro ATX case, the Define Mini C and its optimized interior provides the perfect base for users. The open air design offers unobstructed airflow across your core components with high performance and silent computing in mind at every step.
Extensive cooling support via both air and water are offered to make sure even the most powerful systems can be cooled effectively. Carrying signature Define series traits, the Define Mini C brings with it that iconic front panel design, dense sound dampening material throughout and ModuVent technology in the top panel. Those wanting to remove the ModuVent to add more fans or a radiator can install in its place the new magnetic dust filter and a built in power supply shroud helps offer an unmatched level of cable management.
Our team of engineers in Sweden made sure performance without restrictions was paramount. With innovative design, the Define Mini C brings your system together in a truly exquisite way, reminding us why we choose Fractal Design.
