since im doin liquid for my gpus i wanna see some opnions. also si9nce this is my first lc system besides a thermaltake kit i used on another rig. im thinking maybe a 3/8 id hose if i can i think the higher flow rate of that size will transfer heat very well but it all depends on the case once its all back together. also what color of coolant should i run i have a uv led coming with the radiator and i was thinking green for alien but theres all sorts out there
