I got rid of it "now" (manners go a long way you know).
following the rules helps aswell
Also, the reason for not using two of the same blocks is because I simply cannot find another EK Copper-Plexi block for a reasonable price; They retail for at least £100, where as the XSPC retails in at £50.
Thanks for the tip with angled fittings though, I've never done any water cooling before and didn't even know they existed. My only concern is that the cards are so close together that getting tubing onto the connectors is going to be difficult.
