Cooler master is a global provider of Cooling, Cases, Power Supplies and Gaming Peripherals. Cooler master also owns the CM Storm, a subsidiary brand created in 2008 with products developed using research collected from partnerships with gaming organizations in e-sports including Mouse sports and Frag Dominant. Think Cooler. We're all about the things that make building a PC such a rewarding experience. The sense of achievement. The joy of making and creating something uniquely yours in form and function. The freedom that comes from complete control. And of course, the thrill of bringing your creation to life without melting your components. 

MasterBox Lite 3

Not everyone has space for a larger PC, but going small doesn't have to be a massive trade-off. With this Micro-ATX case, we've added a few ways to give you more room to work with.


Challenge the confines of the MasterBox Lite 3 by utilizing its flexibility to free up space for larger components. With an optical drive cage capable of meeting all your storage needs, the rest of this case's interior is open space for full-sized graphics cards and cooling normally reserved for larger cases.


Have the freedom to create a PC that suits your needs in a size that works for any space. With an easily configurable layout you can build a system that fits anywhere with the components you want.
