Having experience of not so long ago done my first build, a bit of advice would be to have your loop planned, but be flexible, as for instance you may find, when you fit the bay res if your rad connections are at that end (front of case) depending on positioning it may end up being too close together to route this way, so you may have to change order to as Cleeecooo said or get creative with bending.
Example being if you click my sig and look at my build (3rd pic) and see how I had to route the tubing from my CPU to my tube res around it almost, in order to prevent kinking
