Mac Users: How to tell if a G5 is refurbished?

I heard from a used Mac dealer that if a Mac computer is refurbished, most of them will have an "RM" added to the beginning of the serial number. Can anyone verify this? Does anyone have a refurbished Mac (especially a G5) with this on it?

Are there any other ways to tell if a G5 if refurbished?

I purchased a refurb G5 earlier this year and yes, mine also has RM at the beginning of the serial No. I didn't know that was a refurbished designation - but I guess it is. I purchcased mine directly from the Apple web site.
