Step 1 of 16: Intro
When the Mac mini went unibody in 2010, Apple made a DVD-less Server edition. In place of the slot-load optical drive was a second hard disk.
With the latest Mac mini (mid-2011), Apple made the slotless mini the only option. This leaves a nice empty space to add your own second drive in non-Server editions. All the pieces are in place except for a custom SATA ribbon cable and mounting screws for the hard drive.
Catering for these needs is the iFixit Mac Mini Dual Hard Drive Kit (www.ifixit.com). This includes all the necessary components and a set of Torx drivers. While you may have a good toolset already, you’re unlikely to have the specialised U-shaped tool that makes removing the logic board a cinch.
The job involves a compete dissembly and rebuild of the mini. But Apple has made this Mac as sleek inside as it is outside and with just a couple of hours methodical work, you can have a dual-drive Mac mini. The upgrade is particularly compelling for adding a small but affordable solid-state drive (SSD), while keeping the original drive for good storage capability.
