This case looks stunning, has plenty of vents and the 2 pre-installed fans have good airflow and are very quiet. I also installed a noctua fan on the other side of the case, which was probably the most difficult step of the build but was still worth it. Overall, the whole chassis is very sturdy.
HOWEVER, the reason this review is only 3 stars is because of the PCIE cable. It wouldn't work properly with either of my AMD cards (r9 380x or vega 56), resulting in artifacting and forced shutting down my PC. Naturally, I asked for a replacement which the team happily provided... Which also didn't work. To say the least, that was most frustrating as I had to build and rebuild my PC quite a few times. I thought there must be something wrong with my setup, so I tried different OSes, different games, resetting and cleaning cable ends and sockets, etc. But ultimately the cards worked fine when plugged directly into the motherboard, without the cable.
I ended up having to buy my own cable as the support team were (understandably) reluctant to send another replacement. I choose a relatively cheap one from my local vendor, which worked perfectly and has been working for the past few months in the same configuration the KKSB cable would not.
Who knows if this is an isolated case or not but this is my review. I hope it helps you make an informed purchase.
