Keep the Mac away from UV light (including fluorescents) and sources of smoke and ozone to keep the yellowing from coming back. Back to FAQ Index 2.8.12 – How can I determine when or where my Mac was made?
Macintosh serial numbers have a built-in date coding that can tell you the week and year in which your Mac was made, as well as the factory in most cases. The first digit in the serial number is the last digit of the year of manufacture. To determine this with certainty will require a bit of common sense (i.e., a Power Mac whose serial number starts with 6 probably wasn’t made in 1986). The next two digits are the week of the year, which ought to be reasonably self-explanatory. The serial number begins with a letter or two in most cases, and this is a factory code. Below is a list of all the factory codes I’m currently aware of; if you can add to or correct this list, e-mail me.
