MasterCase 5
WITH FREEFORM™ MODULAR SYSTEM
The MasterCase 5 Series
At heart, the MasterCase 5 advocates a new relationship that binds component makers and users closer together. Its elegantly smooth, flexible FreeForm Modular System supports multiple outlooks, allowing you to upgrade rather than entirely replace your case as your needs change over time. 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.
















FreeForm™ Modular System
We want you to have absolute control over how your case looks and functions. The FreeForm™ Modular System of the MasterCase 5 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.

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 our unique clip-and-click panel, FreeForm lets users 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 your 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.

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.

and purchasing components through a range of accessories to truly help you Make It Yours.






MasterAccessories List
Each case comes with a different number of MasterAccessories, from our MasterCase 5 with its basic package, to our MasterCase Maker 5 coming with a wider range of accessories. Buying a basic package always leaves you freedom to enhance your case by buying additional accessories in the future.
