did anyone mention that it is big yet? =]

The design is nice. Right now however, I think blocks are heading into a direction that produces more turbulence, high surface area, and high flow rates. I must say that you did a good job if this was your first venture into making waterblocks. The middle piece probably did not have to be so large. Reason being is that I am assuming that you are using plumbers solder which is typically a 95/5 ratio. Plumbers solder is not the greatest when it comes to thermal conductivity. The heat has to fight through that layer of solder to get to that very large center piece. However, I could be completely wrong and after testing you could have produced the most powerful waterblock to ever hit the planet. :P

The block is nice, but we want to see testing results!
