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.




We’re sustained by a belief that something as endlessly useful and diverse as a PC can never really die, and a vision that we can re-invent the way they are designed, made, bought and used. It’s a vision that stems from the core of our company, from our heritage as innovators of the initial strides forward in thermal technology, to our commitment to pioneer a modular future. We’re also committed to keeping our design, testing and manufacturing in-house, to give us the edge in ideas, craft and quality.


We realize people want to express themselves in all the things they make and do. So in everything from components to cases, the way they are configured and the way they look and feel, Cooler Master is committed to giving greater choice and control to you. That commitment is made real in our community of makers and creators. After all, it’s you guys who bring our ideas to life.


We’ll be using this chassis to build our portable gaming/mining rig. The handles will definitely come very handy, especially when we move and transport the system from location to location. Our portable gaming/mining rig will consist of an ASRock B350M Pro4 motherboard (AM4), AMD Ryzen 5 2400G processor, EVGA CLC 280 AIO cooler, 16GB DDR4-3000 ram, 256GB M.2 SSD and TWO, yes 2 x Radeon RX 580 graphic cards. 

Let the gaming and/or mining begin! …
