Product Overview Make of It What You Will
The new wave of case technology pioneered by our MasterCase series crests with the unique FreeForm™ Modular System, which allows unparalleled flexibility to upgrade your case via the addition of top panels or doors, aesthetic customization, varied thermal solutions and internal layout adjustment.

Find all of these in a compact form factor with new FreeForm™ features and the same easy access to customize, adjust and upgrade your system as you wish.

A Smaller Case With Lots of Space

This new compact addition to the MasterCase line is built with the same FreeForm™ Modular System that defines the series. Customize and adjust your case via swappable aesthetics, adjustable layouts and intuitive thermal performance. Improved layout flexibility handles larger components and cooling systems within a discreet form factor.


A case meant for a smaller build that still packs a punch. Build the high performance PC you want in a tighter frame. Its streamlined design with steel and mesh makes this product incomparably stylish. It supports up to five fans, eight HDDs and two graphics cards.

Compact & Portable
Save space and easily transport your build with the MasterCase Pro 3. The reduced size and added top handles mean you don’t have to give your PC the awkward bear hug. Conveniently take your case to LAN parties, special events, and trade shows while still fitting the latest full-sized components.

Cooler Master MasterCase Pro 3 micro-ATX Tower Case, FreeForm Modular System, Handle, 2x140mm Fans, 2xUSB3.0, Dark Grey is rated 5.0 out of 5 by 1.
Rated 5 out of 5 by from Great case but very big for micro atx Really nice case and well thought out. If you want a micro atx case for mobility then I suggest you look elsewhere as this case is big! It's actually bigger than my midi tower atx case. When you do need to move this case, the handles on top are great. Easy quick access to both sides and the case is solid. No vibrations and very quiet. The top will take a 280 radiator. This case will fit an atx motherboard if you remove the PSU divider. Overall a very nice case.
