Pretty straightforward these days! Though I've been doing it for awhile. There a lot of little gotcha's like tubing choice and fittings but once you get the hang of the options it's pretty fun. Though cooling 4090s even with water is hard - you need a good flow rate to dissipate 450W. They'll hit near 70C during training if the fans are kept below audible, which works for me. 55-60C with fans at 50%. This is with 2x420mm (3x 140mm fan) rads and one 280mm rad (2x 140mm fans). The stock heatsinks actually were actually able to cool them just as well, just they where much louder doing so! Power is the other tricky bit. The computer is living on the dedicated AC circuit for now... 1600W is a lot. When it was on the single outlet circuit in my house, I could see each iteration as the lights dimmed in sync with the power draw surging.
