I hope your PSU lives long.  What is the motherboard revision?  Does it have the ROM tower?
My 'UX, which is a very early one says serial number CA1002356, I wonder what the CA stands for....  Oh, and it's the James Bond Edition.  It has a sticker that says "C=007".
I can't get at my other 3000 to see what it says, but it's considerably newer.
