The Cooler Master CM 690 III case does not raise the bar, but provides a solid concept and is a worthy successor of the CM 690 II with a lot of new features that you would not like to miss after first use.
The CM 690 III is not able to match all points of the CM 690 II Advanced predecessor but one should not count the missing features such as the switches for the lighting, the eSATA port or SATA dock, because there are several improvements like e.g. the huge front fan, USB 3.0 ports, modify able hard drive cages and meshed slots. If that is still not enough, you can optimize the chassis for example, with this casemod guide.
So overall the concept is consistent and allows a comfortable building of a PC with very good air ventilation and thus offers the opportunity to reduce the speed of the built-in fans to a minimum. Of course, the chassis is not very silent with so many mesh sheets, but it can cool down easily within a short time, when the PC is for example used for gaming.
All in all, this Cooler Master CM 690 III Mid Tower case is really awesome and earns the must buy award for overclockers, the very important Redaktion ocinside.de OverClocking Dream Award 02/2014.
