Thanks for the advice guys.
Heres some of my reasoning for the setup, it might be wrong but I'll give it a go,
With the Rad sucking cool air in, it seems that the optimal placing for it as long as I can manage the dust, is at the bottom. Also I figured there'd be less water/air bleeding problems?
With regard to the rear fan intake, I might have to rethink this one, My initial thoughts were, if I could have the PSU drawing in cooler air, the PSU would stay cooler, keeping PSU fan speed down, also it might cool the mosfets a tiny bit. But it's all just guess work.
Note, just to be clear, heres the order>
PUMP > RAD > CPU > PUMP > FSB > RES
Arcturius, is this recommended, I've read bad things about it regards PSI / flow / pump redundancy etc..

And yeer, I'm a bit worried about those 15Kers, but I found them cheap and couldn't resist.
