Great guide. When you are prying the glass screen off be extremely careful not to lift the top of the too high. If you do lift it too high then the glass at the bottom of the phone will easily crack.
When re-installing the original hard drive (aka - inner hard drive), be sure that this drive's two side pins fit exactly into their rubber mounts that are deep inside the Mac Mini.I achieved a nice fit by turning the Mac Mini on its side so gravity would align the pins with their respective holes with ease.
