Great Job anguish!
A video makes it so much easier than trying to explain to someone what they are in for.
I hesitate to add anything because I don't want to detract from the awesomeness of your videos.....but I'll add just a little....
For the keyboard... Once the three screws are out, the only thing holding it down are the clips on either side. So if you begin prying in the middle near the F8 key, it will flex just a bit and help the clips release. As you cautioned, care is needed when prying on the keys themselves; they will pop off (don't ask...LOL).
Then what I did, since I'm constantly swapping hard drives, is to put a little piece of tape on the back-side of the keyboard up near the F8 key so it sticks out from underneath a little and makes a tab for lifting the keyboard.
Again, kudos.
