This build has been progressive. It started with the i9 9900k and a 2080 extreme in December if 2017. Its evolved into this rock stable behemoth that runs at 5.3 on all 8 cores all the time, an additional $1600 in ekwb cooling, and an additional LSI Raid Controller. Along with gaming, I use it as an everyday computer and feed my ever growing plex library with it. It's regular cooks with 8 hour sessions of Handbrake crunching as well as being able to game most titles maxed spanning 3 4k displays (yes I do get some lag doing it, and if I'm serious I drop down to 1440 to keep the fps up) If you want to enjoy ray tracing you have to ditch sli, and drop down to one monitor. PC Part Picker is wrong about the drive cage GPU conflict, there is space for a 120mm noctua with a Phanteks Ring attached between the hard drive cage and the 2080TIs. Along with the obvious water blocks there is a 240x60 radiator on the bottom and a 480x30 in the top. 480cpu 240 gpu parallel loop. The D5 is tucked into the unused portion of the 5.25 bay area. The only Nlink adapter I found was the Asus that works with the ekwb blocks without mods. I also regularly do 10gbs file transfers to my home server with this rig. Other items to note are the 13 120mm fans and 3 140mm fans all noctua with Phanteks digital rings and control. When I'm pushing the CPU it can get loud but for gaming and normal use its quiet as a mouse.
