Power supply and distribution. Just an idea so far.....

I estimate I am going to be using about 1.2kw@12v so have been looking how to supply and distribute it.

My current plan is to get this 1500w power supply and make a power rail to run along the top of the water block.
I don't have much experience with PCB software so was hoping someone could help out with this. The idea is to sort of staple a heavy duty cable onto a pcb using link wire and soldering it to the tracks. The pcb would just be a repeating pattern totaling about 600mm long so you can snap it off at the required length. The stripped cable would be 'stapled' to pcb both top and bottom.
