This is my second attempt at a full custom loop, I wanted to do something clean with an industrial feel. Last time I went with colored liquid and it just gets boring after a while as it makes you commit to a particular color scheme. I went with clear pre-mixed coolant by XSPC, this stuff is great, last a while and never gunks up my water blocks or pumps. I moved most of my components over from my last PC including the power supply, storage, CPU water block, and GPU. The rest was all new. I am really loving how this turned out and the i9 9900k heat is tamed by the dual 360 rads, at 5.1 Ghz it stays well under 80 while gaming.
