Hmm... I have to say, frosting tubing and res might be a bit overkill... But I've never exactly been a fan of the frosted circles thing so I'm a tad biased. Frosting the tubing alone sounds like A good idea, as long as you don't mind losing the jet-black coolant look. It would make it more of a flat black were the tubes frosted. Two, that stands to be ALOT of repetetive and monotonous work.
