Focusing on a more 'make-your-own' product philosophy, the MasterCase 5 gives you the absolute control over how your case looks and functions. Its elegantly smooth, flexible FreeForm Modular System allows you to customize and upgrade your case's form and functionality with multiple interior and exterior accessories*. Meanwhile, whether in hardware compatibility, expandability or cooling performance, the MasterCase 5 doesn’t make any compromise.

Go with either basic dual top handles and standard door of the MasterCase 5 or an elevated mesh top cover of the MasterCase Pro 5.

* Accessories may not be included. Please refer to the specifications.

FreeForm Modular System

FreeForm Modular System lets you adjust the exterior structure and aesthetic via a range of replacement panels and doors. Each choice changes the look and feel of the case, but also the flexibility of the interior layout.

Customize with External Modularity

Easily customize your case by adding a top cover and water bracket for a new look along with liquid cooling radiator support, freeing up space inside the case. And if you want to show off your system, a window side panel is also available. These options are included in MasterCase Pro 5 version or available separately.

Adjust Internal Layout Clip-and-Click Panel

But this isn't just about aesthetics. Each decision opens new possibilities.

Leveraging the unique clip-and-click panel, FreeForm lets you vertically adjust or entirely remove your optical disk drive (ODD) and HDD via sliding locks. So intuitive, you'll play with your configurations just for fun. Well, some people will. Just click-in the cages, and adjust the height to suit their needs. Position them at the top to allow room for up to three extra-long graphics cards, or retain only the bottom positioned cages to add a front-mounted radiator for even more cooling options.

Integrate replacement accessories like:

  • Fan brackets
  • Water cooling reservoirs
  • GPU support brackets

Slip-and-Clip Pockets

The first Cooler Master case to incorporate two easy to install slip-and-clip solid-state drive pockets (2.5") with four easy mounting positions. Showcase them on the partition panel or hide them behind the motherboard tray for a cleaner look.

  • Two behind the motherboard tray
  • Two on top of power sup

Unmatched Ventilation

FreeForm enables the option to install three front-mounted 140mm fans and a 280mm radiator for unmatchable ventilation due to a unique facility to horizontally shift the bottom-mounted hard disk drives. There's also support for up to six 140mm fans through the case, unique for a mid-sized tower.


FreeForm extends beyond the case to include all the support you need in terms of selecting and purchasing components through a range of accessories to truly help you Make It Yours.

Each case comes with a different number of MasterAccessories. Which MasterCase is Right for You?
