Need for more memory and speed from the hard drive.
A few hiccups but otherwise smooth.
1) Have a system in place to keep track of your screws.
2) Clone the old drive to the new one before you do anything else.
3) Skip step 11 as suggested by others.
4) Lock your 4-year old in the closet for the duration of the repair. ;-)
