As long as it's not green I think I'll be fine with either.
And this is where we differ, I would *LOVE* a green one! A purchased a Satin Black with Blue LED and I love it, amazing device, but if the options were Red, Green, or Blue, it would've been green all the way!
My computer is housed in an Antec 1100, with 5 120mm Green LED fans, my keyboard is a Logitec G19, set all to green, my mouse is a Razer Naga Elite, again, all set to green, see where I'm going?
