Got the measurements, and by the end of the weekend i will FINALLY be home.  Then I have some BSOD's on my CAD computer that my wife may have had something to do with  (grrr)

Nate I would like to sincerely thank you for making this part.   I recently joined the forum after ordering a Dark Mobo (which arrived today).    She will be on air cooling to start but this will be my first liquid cooling build.  I have heard nothing but GREAT things about your work.

I was running 4.5Ghz on air with my E8400 (Good mobo, cooler, running lots of voltage but not 'TOO MUCH').  VERY hot yet stable.   I finally feel I am satisfied with air and it is time to move on.   This time I have a CLEAN brass car radiator to use.  It was 'free' and I suspect the rad can be fanless and still cool!

I am likely 2 - 4 months away from the conversion to water,  but I am stoked.   I will be buying one of your waterblocks to ensure I do not miss out on the opportunity.   Thanks again

Very simple design and I'm sure quite effective! Knowing this will be available for purchase leans me towards purchasing a Dark over Asus X79 in the next few weeks. Looking good!

I plan to keep it as simple as possible. 

nateman-doo, question for you, what copper are you using?
Soft? Half Hard? Hard?
I have access to engraving machines/CNC's (used to run them when I was younger)
and am thinking about making a block for my GTX780.
Also, what are you using for your ring seals on your blocks?
 
Thanks in advance bud
 

Cu110 (99.9% pure),  so I guess I would consider it soft.  The O-rings are Buna-N

Thanks nateman

The backside:

 
I would love to have the board for test fitting.  Anyone on the east coast? Near Jersey?

I'd love to help, but I wont be getting the board much before October.  
 
 
I do have another question though.  Will this block come with a clear or black top?
