- Would Apple's Lion installer accept this newly upgraded iMac as valid install target?
While this guide says you can only use low profile 9.5mm tall drives, you can absolutely use full-height drives in this iBook.
To use the full-height drive, do not replace this metal bracket with the padding. This piece is to provide stabilization/p
adding for the low-profile drives Apple uses in this iBook.
With a full-height drive, the polycarbonate case and RF shielding material rests against the drive with no space, keeping it still.
Just installed my full-height drive by omitting this piece, and the case fits together perfectly and iBook is happily up and running.
