Yes, you really need one depending upon the Mac your working on:
1: A green or dark cloth to see the tiny screws and a method to catch dropped screws while working on a Mac, like a large flat tub.
2: A container with numerical labeled sub compartments (inside the tub with the Mac) to hold one screw which a list is maintained which screw goes exactly back where on the operated Mac as they look the same, but can vary on length, type and size and thread type. No extra screws available either.
3: A written list of how to disassemble and reassemble, because you certainly can't boot from the Mac and watch the video.
4: I think it's a #10 torx micro driver too, to really get into the guts of the machine. Which certainly would void your warranty/Apple Care. Not needed for the recent MacBooks of course, which the drive is accessible through the battery/RAM bay and a few screws, so it's a user serviceable part.
5: The correct size Phillips head micro screw driver needed, not forcing a blade of a knife or a wrong size screwdriver into those finely machines screws, stripping their heads.
6: Assorted magnifying glasses and magnetic pickup tools, tweezers and such for micro work.
Apple should make all their laptop drives user accessible. A little screwed on door and pull out the device, slide in a new one (or the old one, hehehe)
