Some of my configurations keep coming up as "Part number: Z0GP" in the cart. Is that the part number they have assigned to them when they ship, or is that something for the store and they would retain their original part number despite upgrades (ie: "MC024LL/A" for the 17" i5)?
And does anyone know if the part numbers mean? What do "MC", "024", "LL" and "/A" mean for that example?
