Of course, I'm not an expert (to be honest, this is my first build), but the case is quite decent. I don’t really understand NZXT fans, because there are neither normal filters for you, nor functionality, and the design of fractals is better. I liked the case, but in order for the temperatures to be good, it is advisable to add two 140mm turntables to the front panel, and this increases the cost and you can already think about buying the same r6; it's better in almost everything except temperatures, Meshify C is still very cool.
