With input from the enthusiast and case modding community, Cooler Master has embraced the maker concept with the MasterCase series, which offers modular panels, handles and an internal mounting system that can also be used for future accessories, such as reservoirs, air channels, GPU holders, or more. This all falls into what CoolerMaster is calling 'The Freeform Modular System.' This system is very intriguing, but it will ultimately be up to Cooler Master to release modules that sustain the viability of the system and convince end users that they are fully supporting the modular concept of the MasterCase series. With the slogan of "Make It Yours" being used for the MasterCase 5, we are interested to see what Cooler Master has in store for those who purchase their MasterCase 5, as the current upgrade options are limited to what we are reviewing today.
