There are a couple of things decided:
Rad is coming inside the case. I will buy a 360 rad instead of my 240.
Then there are some questions left unanswered 1/ The top of the GPU waterblock will be black, should I go for red fittings? 2/ Rad is black, should I go for red fittings? 3/ Bottom of the pump is black, but the top is plexi with red dye in the water, which color of fittings should go there? 4/ Should I take all black or all red fittings, or is it a good idea to mix them? 5/ I can make the tubing straight and parallel to each other to create that nice and clean look. But I can also make a kind of 3d piping inside the case by letting them go under and above each other. What could be best ? I doubt the 3d effect will be even possible because of the acrylic that doesn’t seem to be easy to work with. And I don’t want it to look messy.
And now some pictures pictures 3d piping effect:
