Too bad they're so darn yellow. That's about the maximum yellowness I've usually seen. Notice how yellowness gets to a certain point, and then it begins to turn brownish/tan.

I have a boat load of IIsi Macs that are brown. They had some company stickers on them which I removed and there is a HUGE contrast where they used to be.

A yellow/brown Mac is much better than no Mac though I must say!
