wanna buy my dd maze 3?
its just sitting here now since i could not fit my cooler into my new case...gonna have to start over.
i'll say this ph if you can see corrosion on the bottom then that block is not long for this world. If its managed to get to the outside then you have extensive corrosion in those little ridges you can see in tex's sawed open one. it had to fill those slots with stagnant water, and corrode the mechanical seal to the point that water could fill the next chamber...and so on.
