I'm a DJ and of course I'm trying to be original, so I'm looking at doing the backlight color change of the keyboard by inserting a bit of colored transparency paper (clear colored plastic) between the light and the keys. I don't want to void the warranty though. BUT as far as I can tell from just about everything I've read, it wouldn't technically void the warranty for these reasons: It doesn't damage or remove anything with a serial number on it. As long as installation doesn't cause damage, we're good. It wouldn't affect performance in any way at all. It's only a cosmetic change Yes, it does open up the case, but as long as it doesn't do damage this shouldn't be an issue. The point is I don't want to void the warranty and I think I'd be good, but I just want some other people's input.
