External SuperDrive

[Tea-Aholic]

Hi everyone.

I just need some help here and would appreciate if someone can point me in the right direction.

I have a MacBook aluminium (before the made it the 13" Pro) and I have taken the SuperDrive out before. If I want to remove it and make it an external SuperDrive do I just buy this and place it in to make a external USB drive? Do I need to buy anything else?

And out of these two, what are the differences?

Thanks so much!
