I think I have exhausted my search for an answer to my current dilemma.
I am a retired Government IT specialist so that may explain my ignorance as I worked in a mushroom farm at a government facility.
I retired and moved from AZ to GA a couple of years ago. I had my computers shipped by professionals so you can imaging my computers were stolen. 7 cents a pound for the loss.

Anyway, I can only locate the original serialized plastic case and the controller, so I have enough to prove this is not piracy.
I am in the process of building a computer after using a laptop for the last couple of years. Most upgrades require inserting the original licensed product before upgrade is authorized.
What can I expect from G5 to make an upgrade vice a complete buy of a new disc?
