I haven't build a PC in ages. Five years ago I saw the Corsair Carbide Air 540 an knew: My next build will go into this cube. It took four more years until I decided to build a new PC. And even I started air cooled, I knew this case is supposed to hold a custom loop. So I learned to water cool and got rid of my Alpenfön and -later on- of the GPU air cooler. I know, especially the bottom part of the tubing isn't as neat as it could. I have to fix that one day. Does anyone of you have any suggestions for further improvements?
