How to account for variations of a computer model?

Hello everyone,
     We order a few different variations of the EliteBook 840 G1. How do you account for these? 

Below are several different EliteBook 840 G1s:
  • J2L66UT#ABA
  • F2P21UT#ABA
  • F2Q28UT#ABA
  • J8U01UT#ABA
      One consideration was editing the Product Name. I don't want to do anything that's going against the grain of the SDP product however.

Thanks!
