It is very high quality workmanship, but certainly not what you want. It has water jacket where you want to put screws through it and the fittings come out the top. Plus, the internal surface area really isn't that large. For my blocks, I plan to carve a kind of "S" shape so the water is in there for a while. Either that, or I'll just drill 4 holes side-by-side long ways through a 1/2 blank and use copper tubing to turn the 4 circuits into 1.
