Good job, really liking the white case, it's interesting what you learn along the way
I'll admit I'm no expert in watercooling but it seems odd to me you have the loop going from the Res > Pump > Radiator top > CPU / GPU > Radiator baydrive > back to Res.
Wouldn't it help temps to have it Res > Pump > CPU > Radiator top > GPU > Radiator baydrive > back to Res. Why would you need it going to the radiator first from the pump? This would lead to increased GPUs temps as it travels down from the CPU. Unless your overall temps are fine and I should be asleep already! My own CPU only loop is Res (XSPC X2O 200) > Pump (EK DCP) > CPU (EK Nickel Plexi) > Rad (Black ICE SR-1 360) > back to Res.
