Ok. I will look around then. Will perhaps go 7/16" ID - 5/8" OD then, if the tubing size doesn't make such a huge difference. Going to price it all up tonight, not that I'm buying the water stuff for a few months, but I need an rough idea of what it is actually going to cost me!
As for the rest, once I get my loan in, I will be buying the AX1200 and the GTX 480. So expect movement on the building. October will see the cabling get tidied, when I take delivery from Nils at MDPC-X. Nice cable braiding will take place then
The rest of the build is still put back, but like I said, planning is still on going. Can tweak as I go.
Update: I had a weak moment, and thought about buying a TJ07. Then I realised, that my current case is just as big as a TJ07, and I really didn't need it
So, keeping the 840, seems like a fun case to watercool. Maybe a TJ07 can be on my list next year if I still want one.
