Just wanted to note that the NZXT Z63 was replaced by an EK-AIO 280 D-RGB. It was on preorder (to the USA) and didn't arrive until well after the build was first put together. On paper, the EK doesn't fit, but it stays tightly enough in place even if the rear 2 radiator mount screws are left off. The CPU socket position on this motherboard required the pump block to be mounted with the tubes facing right, so I couldn't keep the original routing under the PSU.
All Arctic P14 fans have also been replaced by the EK Vardar S RGB fans that come with the EK-AIO D-RGB kit.
