This is my second hard tube water cooling build that I finished in summer 2022. I chose a compact case, and managed to put three radiators in it. That came with some challenges: had to trim the case, trim the cable connectors and even add some extra bits in order for everything to fit inside. And of course, the biggest challenge was to bend the tubes. In the Asus Z11 case, the motherboard is tilted 11 degrees, as a result I couldn't use simple 90 degree bents and had to calculate precisely each angle. Also the bents are very close to each other. All in all it took me six months to complete the build, I'm quite proud of my work.
