Inspired by CrazyTechLab's Evolv Shift mod I set out to do my first custom loop simlir to that.

Requiring waterjet cutting and an angle grinder I could fit 3 120mm radiators and 5 120mm fans (2 push/pull bottom intake, 1 back intake and 2 front outtake).
As the Radeon VII is crazy big I had to move the PSU outside the case (mounted on the rear panel). But this allowed me to mount the GPU all the way to the right and have the tube coming in straight from behind.

Running some graphics benchmarks the CPU sits below 45C and the VII below 55C with the pump running at 30% and fans with a very conservative profile.
Filling the loop was a little tricky as I've chosen the drain port for in which leads to air from the loop being pulled right back into it again. The Alphacool radiators additional fill port on the back were quite helpful here.

As my boards wp header has enough power I've removed the molex connector from the water pump and rewired power to the PWM header too. To fill the loop I've used a little PWM tester from AliExpress.
