Identify which license is on which PC

[KLP34]

I have four notebooks and four Office 2003 licenses (boxes and disks). All
bought at different times and installed then the boxes were shelved.

I'm trying to match up the programs/licenses with the notebook they're
installed on because the hard drive on one of the notebooks failed and I
replaced it yesterday. I want to install Office 2003; however, I don't which
program disk to use.

Any ideas? Is this something I should be concerned with?
