I have a Z4 block from OCH....its the older version with the 3/8 barbs. I don't have a problem with the product or OCH. The block was well machined and needed only a slight lapping to remove some machining ripples.
It has excellent flow with a Danner 350gph mag drive using 7/16" tubing. I have a big radiator(mack truck A/C condensor) with 2 120mm fans mounted on it. Running my Duron 1.1 @ 1.90 volts and 8.5 x 150 for 1275 mhz ,chip temps are 26-28 c with a 22 degree ambient. Water temps run 2-3 degrees under chip temp.

I read the thread about the Z4 block having 1/2 inlets being screwed up.... I agree that was bad business, but hopefully that has been redesigned by now. The sump pump in the container idea sucked too....I may try something like that at home, But I wouldn't try to market it as a reliable pumping solution.

Basically... if you haven't bought something from OCH and been dissapointed...don't bust their balls just to join the bandwagon.
