Before buying components for assembly in this case, I read a lot of reviews, reviews and documentation for the case. Nowhere! I did not find any restrictions on the thickness of the video card. As a result, I bought a video card with a massive three-slot cooling system 55mm thick, which simply did not physically fit in the case, the radiator stuck out from the outside. Empirically installed, the case allows the installation of video cards up to 40mm thick. It is advisable to use a 140mm power supply in order to use the free space for cable management. I recommend to buy. Node 304 allows you to assemble a compact yet powerful gaming system.
