The OptiBay and the drive I am going to use:

What you get in the box:

You get tools to do the job when you order this kit:

Lay out the screws this way so you know where to put them when you are going to assemble the laptop again. Note the three longer screws. (I often use a sheet of cardboard for this - drawing an outline of the area and pressing screws into the cardboard at the locations they were removed.-Mike)

The insides, Apple has done a good job on the layout. The Unibody macs are easy to fix / upgrade.

Taking out the superdrive. Again, very easy to do. You get good instructions along with the optibay purchase..

The harddrive mounted inside:

Superdrive replaced with optibay:

Two harddrives in a laptop. Nice.

After the images was taken I decided to buy two Intel 2.gen 80GB SSD drives instead. I also decided to JBOD them. With an active Time Machine backup of course!

A fun thing to do a rainy afternoon... or cold / snowy here in Norway. Take care people.
