The Gateway to Stylish Gaming: Customizable Trim Colours!

The MasterBox Lite 3.1 mATX Case is your straightforward option for your PC build that doesn't ignore good looks, customization, or performance. A sleek DarkMirror front panel and three custom trim colours (included in the box) offer a great first entry point for customization. Additionally, it comes with an edge to edge transparent acrylic side panel to show your internal components. And with support for up to 3 cooling fans and a water-cooling system, we ensure your performance will not suffer.

3D Printing: Freely Express Yourself
We know the community also has some awesome ideas, and the ability to express them in everything you make or do. So with that in mind, we've released the 3D printing schematics of the top and bottom trim. These are available to download from the CoolerMaster website.


DarkMirror Front Panel: Stand out and be unique. Your case doesn't have to look boring.
Customizable Trim Colours: Choose from three distinct colours to suit your style, all included in the box.
Edge to Edge Transparent acrylic side pane: Show off your first build in style, and have easy access to your components in case things go haywire.
Full Black Coating: Let your system stand out with an all-black background.
Support for 3 Fans & Watercooling: Three 120mm fans and front watercooling support ensure that you don't have to compromise on performance.
Graphics Card Support up to 380mm: You won't ever have to worry about the fit of your graphics card, with support for even the largest, widest cards.
