About Coolermaster

Coolermaster invites refits from around the world to join them in the biggest refit competition of the year. From customized game consoles to mechanically modified machines, everyone can showcase their latest and greatest products. This year's competition encourages modifiers of all skill levels by introducing two different categories, the master league and the apprentice league. They will invite expert reviewers to carefully evaluate the design, technology and craftsmanship of each project. Coolermaster is open to everyone, regardless of skill level. Whether you're a beginner or a CNC master, every league reflects the way you want to compete. Either go all out for fame and fortune, or join in the transformation of the community, no pressure, all fun. Experienced refits know their mechanical development and are ready to be the best in the competition.
