hi, gonna be making a NB block, i just need some suggestions on the design,

the materials i will be using are a copper base and brass water housing, i have to use brass housing b/c the copper i have is about 5mm thick so its good enough for just the base,

since the brass will be the housing, the way the water flows inside will depends on the design i drill (i'll be using a drill press) in the brass, so my question is, what would be the best design to drill into the brass? i was thinking of just an open design like the swiftech block have, OR a U shape.

as for the base, here is what i came up with, i will be drilling pits into it,
