just noticed something bizar: that GTX280 that's going in is already equipped with a waterblock by the factory and already overclocked.
and still, you add another GTX280 waterblock from XPSC. did you replaced the stock block with that one from XPSC, or is it a reserve gadget in case the winner would like to go SLI?
and will that 240 rad be sufficient for both a i7 proc and a gtx 280? but I did hear that those rads from that serie from XPSC perform rather good, read excellent, with low-rpm fans.
