The buttons and keycaps were a little lighter than the outright brown of the beige version (for a non-yellowed platinum, think the color of a nice Starbucks frappuchino) but were still a nice contrast to the rest of the case. I think I might like the two-toneness of the case more than any other element now that you mention it!

I need to get a dust cover (or get someone to sew me one) for this machine to protect it from the elements--I used to have one but gave it to my cousin! Anything to prevent this little guy from yellowing would be great!!!

Yes, I do plan to use it once I move into my new digs and build a desk for it (while I'm still at my current place where my power tools are).
