Block has been installed and running for 3hrs now. With the Duron 1gig@1200 1.8Vcore it is holding 36C with SETI load and 18C room temp. Water temp unknown as I lost my probe.

Not 100% sure I mounted it well and it definatly needs a little more lapping. I also mis-measured and the middle inlet is only about 1/2 over the core.

So it has a lot of room for improvment. I am also using an SUBMERGED 200GPH $15 pump. Flow is very maximized though. The system is not in a case and all hoses are very short and no tight bends exept for one sweep 90 on the heater core. Lots of water coming out the dual outlets. I can't say I am to disapointed yet as there is a lot to modify on this to make it as right as I can. Move the inlet over the core, lap the bottom better, and add a nozzel. Honestly though I will probably not do much more with the Pyrmid pins as it will probably not be possible to use that engraver for it in the future.
REV. 3.0 will be a drilled version and I am going to work with that as I can do that with my own equipment. My little cnc is just perfect for making a precision drilled base.
