Any chance we can have the option of copper fins or black fins. Personally I like the black because raw copper oxidatizes and looks like crap unless you polish it once a month.
There are ways you can modify copper so that it doesn't visibly tarnish or oxidize... but the process require adding brighteners to the copper which can get costly quickly or require special plating tools again, can be costly depending on the end use conditions of the copper. It will still oxidize, but you won't see it as a dirty copper color or green. It's really commonly used in the semiconductor industry, but it's unlikely you'd see it on a copper radiator for a computer, due to cost.
I personally like the all chrome/silver one, but I'm boring.
