Right, I have had a look around and read through that article you posted for me to have a read. I have come across with a selection of objects that I think are ok, but would like some more input on all/some if necessary and whether you think they are anygood for my current system.
CPU Water Block: DangerDen TDX Block for A64 1/2" ID
GPU Water Block: DangerDen NV6800 Block 1/2" ID
Pump: Swiftech MCP655 12v DC
Reservoir: Not sure on what reservoir to get 
Radiator: Black Ice Xtreme III Triple 120mm Radiator
Tubing: Tygon 1/2" ID 11/16" OD Laboratory Tubing #R3603
Clamps: Breeze Miniature Hose Clamp 7/16" to 25/32"
Fitting: Not sure about these, may not need any... Though I may be wrong 
The route I will take will be like this, or what I think will be ok:
PUMP > CPU WB > GPU WB > RAD > RES > PUMP
I think that should be ok, if not, please do correct
Hope you like them all and if you think you can find some better objects please be sure to post them and I'll have a look, as you can see from above... I don't know what reservoir to choose from as I wouldn't mind a fair decent sized reservoir, not too small and I don't mind having it out of my case either.
As for fittings, like I said above I may not need them but who knows?
