That is good to hear!

ok update.  My leak came back :( and I emailed monsoon.  He was very nice and sent me new orings and a pump head.  Thank god he sent me a pump head because the one I had was defective.  Upon disassembly, I found that the pump head had small circle defects from casting and that was causing the oring not to seat.  I have pictures but photobucket is down for maintenance so I can't post them right now.  I am in the process right now of switching the head over and then reassembly.  Also for whatever reason my LEDS in the CPU block stopped working so I am going to remove them and try to replace them.

 
Ok thats the defective pump top.  You can see the little circle indents from casting, they sit right under where the oring seats.  
 

 
You can see the replacement top doesn't have these circles and is smooth.

here she is pretty much together.  Ignore the SLI bridge, I have a couple of ideas for it that I'm working on.
 

Great work on this mod.
