Great job upgrading the original 2017 One, I've just upgraded mine to an EVGA 3080 XC3 Ultra with the SF 750 PSU thanks to many of the members here providing insights. But it is extremely nice to see you journal out your upgrade with photos. On top of what EchoSierra said, I've actually just plugged the top case fan to the CPU AIO pump since corsair left that cable unused, and the only modification I did was to install the fan with it rotated 180 so the cable was long enough to be plugged to the case fan. Corsair Link was able to read the fan alright with nothing that needed to be tweaked. I plan on doing some cable management since I used 0 cable ties when I upgraded mine, maybe I'll journal the CPU side so there will be more info on this amazing first gen case for those who are looking to upgrade.
