There are some minor hardware differences depending on when you bought your deck and random chance. If you buy a brand new deck for example you may find you have a different heat shield than in most of the older tutorial videos for the deck.

Another example of differences is that two different styles of thumbstick were used, and until recently you were limited in what replacement thumbstick upgrades would work depending on which type you had (now they have universal upgrades that work with both kinds).
