This build is the result of adding a PETG waterloop to an air cooled Ncase M1 build I did in 2016, as well as upgrading from a 1080 to a 2080. The purpose of this was mostly for the aesthetics, since an optimal air cooling setup in the M1 would likely match or beat my results. Still, my temps are significantly better than they were previously:

-CPU Idle: 30C
-GPU Idle: 30C
-CPU Load: 70C
-GPU Load: 66C

These results are based on running 1 hour of OCCT and 1-2 hours of continuous gaming, with a 21C ish ambient temperature. I've also removed the glass from the windowed side panel since the GPU block sticks out a little too far, which should be helping with airflow.

Something people might question is my decision to water cool an i7-6700 paired with a pretty cheap motherboard (Gigabyte H170N). My hope was that this would allow for more effective cooling of the GPU. I also saw no reason to spend the money upgrading my cpu/mobo, since the 6700 still seems decent enough for gaming.
