another 2 cents
Looks like your going pump rad / gpu / rad / cpu/ resv / pump.
You should really hit the CPU before you hit the GPU. Why not
pump / cpu / rad / rad / GPU / resv / pump
or
pump / RAD / CPU / GPU / RAD / RAD / resv / pump
Either one would shorten the amout of tubing which would increase the flow. That's long single loop. You way should work too, just more burden on the pump.
looks bad ass the way it is though
