Here are the pics, finally

:
The radiator was painted by me using thermally conductive paint and as I said before, the shroud is made of 0.8mm galvanized steel, it was calculated so the fans stay 3cm away from the rad, I haven't really read any studies on that but I think that's a good distance.
In this last pic I tried to demonstrate how little the flow restriction is with this block, you can see the water hits the wall opposite to the inlet of the reservoir with some good pressure, the video shows that much better than a pic but I didn't think people would go to the trouble of downloading it so..
The reservoir (like this one) will be available with the 2nd batch of the block and I'm trying to work something out for the rads, as I can't be making these shrouds manually or it would take forever.
Please post any comments/questions you have
Thanks
