...that could determine your Mac's manufacturing date based on its serial number? I swear that I remember System Profiler showed that at one time, pre-SL. Both of the minis here are refurbished, so their serial numbers begin with RMxxxxx.

My ASP doesn't show the manufacturing date, I would like to know it though.

Found one which narrows it down to month and year. My mini was refurbished in November 2008 (it's a mid-2007 model).
