LED build looks nice so far. Heads up on the copper though, while it's thermal conductivity is better it's capacity is lower so more dependent on fans for convection. However the reason you'll never seen copper heatsinks for aquarium LED fixtures is because unlike aluminium it oxidizes quite rapidly with a little humidity, especially with salt. So blowing air from around your tank will quickly cause the surface to oxidize and make the heat sinks less efficient.
