Well I am building a rig right now, I have a Coller Master Stacker 830, and want my water cooling to go through my 8800GT (when I buy a waterblock for it) and my CPU (Q6700).What kind of loop are you looking for?
Budget, components wanting to be cooled, what particular components you have, what case do you have?
That information will help me steer you in the right direction.
not sure its not listed. what they do say is:Yeh I'm looking at getting my new system water cooled, does Petra ship to Aus?
So just give em a call.petra's tech shop said:International customers: please contact us by phone or e-mail for ordering information as, currently, our online checkout system is not well equipped to handle international orders.
