Customize the Look

Think of the frame as a blank canvas, one that awaits your input to reach its full potential. FreeForm™ lets you easily customize via replacement top covers, panels, doors, and custom-built accessories made directly by makers in our community. Just for you.

Side Window

A clear side panel gives you a direct view of your hardware. Included is a removable tinted window that attaches to the bottom of the clear side panel. This tinted window hides the power supply partition for a clean look. (Included with MasterCase Pro 5)

Top Covers and Panels

Simple yet modern style, but with customization options for you to fully express yourself. Magnetic top cover with plate, front mesh bezel, or padded front door for sound suppression.

Tempered Glass Side Panel

A Tempered Glass Side Panel gives you a clean look of your hardware. Included is a Lock Mechanism to protect your hardware.

Adjust the Inside

FreeForm™ isn't just about aesthetics. Each choice changes the look and feel of the case, but also the functionality and flexibility of the interior layout.

Clip-and-click Panel

Vertically adjust or entirely remove your drive cages. Just click-in the cages, and adjust the height to suit your needs. Position them at the top to allow room extra-long graphics cards, or retain only the bottom positioned cages to add a front-mounted radiator for even more cooling options.

Slip-and-clip Pockets

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™ lets you install multiple front-mounted fans with radiator support for unmatchable ventilation due to a unique ability to horizontally shift the bottom-mounted HDD bay.

Upgrade to Meet Your Needs

Upgrade rather than replace. It's not about what has the best bells and whistles, but which one can easily adapt and change to meet your needs over time. And that means products that have modularity, numerous accessories, and the online support system to help it grow.
