I decided to go for an ITX build one more time.
Problems I encountered during the build, please read carefully if you´re planning to go for a full RGB Mini ITX system:
The included smart hub with the NZXT 210i had one of the led channels broken, therefore I couldn´t connect all the led strips, fans, etc. So I had to go for the Hue+ Controller afterwards in order to get everything up and running.
Not all full size GPU will fit in the case if you have an AIO cooler like the Kraken M22, only 270 mm. long cards will fit, if you don´t plan to have an AIO, any card 300 mm. card like the Asus Strix series will fit in the case. Keep that in mind.
The Kraken M22 backplate touches one of the motherboard connectors at the back of it and I had to chop off one of the corners of the Intel mounting system, so now is fine.
It was a bit of a pain in the *** to get everything connected, but with a little bit of patience and organization you can get it done.
Was it difficult? Yes Would I ever do it again? Absolutely.
