Cooler Master announced three cases aimed at the modding community at Computex 2015. Part of their new 'Make It Yours.' campaign are the MasterCase and MasterCase Pro as well as the MasterCase Maker 5. All of the external parts are modular and easily removed with a clip and click system implemented on the cases allowing you to not only change the configuration of your case but also to modify them or design new ones if you have the tools.
All the cases follow a similar overall design to the MasterCase5 pictured above, a 460mm tall tower, deep enough to fit 260mm radiators and long enough for lengthy high end GPUs. With a half dozen mounts for 140mm fans the case should move heat efficiently and depending on the fans you chose, quietly as well. The MasterCase5 sports handles on the top, though it is perhaps a bit large to be considered portable they could come in handy for cases that spend time being shown off at conventions and shows. The Pro model forgoes the rear handle for an elevated mesh cover good for installing a radiator while the Maker 5 has a solid top but vented front door for those who might want to do their own work to the top. All have a separate bottom compartment for your PSU and drive bays for both 2.5 and 3.5" drives which can be mounted in a variety of ways or removed altogether.
