I successfully took mine apart in order to harvest the hard drive (Apple told me that the unit as a whole wasn't fixable, but that the drive should be good).
However, I got to the point of trying to remove the 4 metal spacers in Step 5 and I can't get them to budge one bit. I need them out in order to fit the drive in the enclosure I got for it, and they just won't move. I've tried a couple different Phillips #00 screwdrivers on them, and no joy.
Any suggestions? Alternatively, anyone know of an enclosure that would work for the drive that doesn't require me getting these spacers out? I hate trashing a perfectly good drive if I don't have to.
