Moring all 
I'm looking into setting up my PC with a upgrade of CPU & GPU, and also at the same time looking to WC it.
I've got my basket full of everything i need other then tubing and fittings.
The Blocks and rads are all G1/4" EK branded threads, do i require the tubing to be 3/8" - 1/2" or 1/2" - 3/4".
And the same goes with the fittings, i shall be investing in compression fittings so same as above with sizings?
Thanks
