I constructed this build with parts from the FLX2 build as I found it too bulky and difficult to maintain (although I really liked it from an aesthetic point of view). But maybe I just wanted to build a new one without buying new parts ;)
The "case" consists of a reduced and slightly modified Fractal Design Meshify S2 case, which was supplemented with parts from the YuelBeast Atlas II case. To be more precise, I mounted the radiators with parts from the Atlas case floating behind the Fractal case, as there would have been no room for three 360 radiators in the case itself.
Besides better handling and maintenance, the reduction from four to three radiators as well as the reduced total tube-length also greatly improved flow consistency. All in all, I'm quite happy with the result - it runs very smooth and cool, even under full load.
