- Putting everything back in place was pretty straightforward, except for the antenna grid. The only way to do it was to twist the grid a little, since you only need a fraction of a millimeter to get the two screws to fit.

Thanks for this useful step-by-step.

My 2 cents about replacing the original hard drive with a Crucial M500 960GB ssd:

- Opening the bottom cover works much better if you apply the force on the whole surface with the palm of your hand, and then rotating, instead of just using your thumbs.

- You don't have to remove the fan connector, just put the fan aside during the whole operation. I would advise against messing with these very fragile connectors, unless you know exactly what you're doing.

- You definitely don't need to remove the logic board, when you've achieved the first 12 steps you can skip to 17.

- The two screws from the original hard drive are very important: you have to put them back in the same place on the new hard drive. Without them the new HD won't fit into the aluminium enclosure, there are two small holes designed for the screws.
