As someone who is considering purchasing a custom finish within 6-8 months (as soon as I pay some stuff off...), I'd love to see such a page. The only problem I see is the color calibration thing. Lemme tell you, the finishes sure look different between my PC and Mac (and yes, I've got the same type of monitor on both).
As a tangent, if I were to buy a system, and I wanted different finishes for the surrounds than the front/center, would that cost more? (I know, talk to Amie directly, etc...)
I didn't do it, no one saw me, you can't prove anything.
