Just finished this and the only things I would add deal with the metal plate that hold the power meter button in is not mentioned and luckily I was able to slide the cable under the logic board and make the connection. otherwise it would be good to add this step before you re insert the logic board. Also the black and orange rubber part that is the bottom of the hard drive mount. They just lift out of the old case and slide into the new case. And there is a metal piece below the speaker that needs to be transferred as well.
Otherwise great guild.
