How do I find out when my computer was bought?

I've had my Mac Pro for a number of years now. Is there a really simple way to find out the exact date when my Mac Pro was first booted-up?

If you have never reformatted/partitioned the start up volume on your machine a get info on /private/var/db/.AppleSetupDone then looking at the creation date should get you within seconds/minutes.
