Here you go...
Obligatory box pic (taken after I finished the build, so not everything is pictured ie fittings, water pump, memory, etc)
Finished removing the GPU air cooler and installed the GPU block and backplate:
Test fitting w/ CPU pump/block installed, PSU, and GPU
Initial filling w/ GPU out of the case to help get bubbles out
Moved GPU into case, bubbles gone, time for real fill / leak testing
Leak testing looks good, buttoning up for final fill before removing the reservoir
All done! (minus case panels, but they just snap on over it)
Close up of the GPU - I had to switch the fittings to go under rather than on top, for both clearance issues and tubing kinking.
Another side view
It's alive!
Temps after playing PUBG for a couple hours followed by some facebook, web browsing, and youtube. Note the "Max" column for GPU and CPU.
