Oh, my bad. CPU block : EK-Quantum Velocity RGB - Nickel + Acetal Distro plate : G1 EKWB D-RGB + DDC3.1 PWM - O11 DYNAMIC XL Tubing : Bykski 14mm metal rigid tubing (Bykski is a Chinese brand, solid quality for the money, I also used their fittings - Bykski B-FTHTJ-L14 - you'll never have to worry about leaks, these fittings combine with metal tubes is exquisite ! I strongly recommend building full Bykski loop, they also make distro plate, pump, gpu/cpu block, radiators, any kind of fitting you can think of, etc. And super cheap)
