Well got the system bleed. took about 1 hours lol ! But it was worth it ! My OC'd Q9550 @ 3.82Ghz runs at 40 idle and tops out at 51 I think that is pretty good before it would idle at those temps and top out at around 62
Watch the opening that your tubes are going through - some of those edges look a little sharp - wouldn't want them to rub through your tubing over time. You might have problems with the pump trying to make the case vibrate. If so, some sort of soft-mounting might be necessary, but hopefully not.
correct on sharp edges use some split loom from canadiantire in auto/electric section or slit any left over tubing an slip it on the edge of steel
for pump vibration can susspend off your L brackets with elastics
