Now my question is if I need to go through all the first few steps in that guide, or if I can just pop it in and format, then transfer my old stuff to the new one?
If you're purchasing it in the enclosure already, you can just pop it in and format. If you were buying the enclosure+HDD separately, you'd need to follow the guide.
Awesome, thanks.
