Ok thanks for all the help, i'll be on my way to get some bodging done sometime this week, i got my own metal case made, however there is 1 problem since my res is a CD Drivebay one will it do being like this:
Pump>CPU>GPU>Chipset>Res>Rad>Pump
Since it won't fit in the case i made

i got the wrong one

and decided to stick with it instead of sending it back. The case will sit on the top of my computer, much like those koolance ones (I think it's a Koolance i saw) so i will pipe it down the back of my case straight to the blocks, upto my Res and then back upto my rad and pump.
Thanks again, i will see how it goes and might post back if i get it goin ok
