You can just as easily damage the machine by replacing the top case with the new lid!
IMOA i'd disagree and find the whole concept of the swap lid stupid. Each time you open the lid you're subjecting your machine to particles and dust (A common ps2 killer)
Installing the no solder mod is childsplay. It is actually more difficult than people interpret to damage the ribbon cables. They are designed to be taken out in the first place (thats what the blue plastic is there for.
Simply use a set of tweezers (if you've got big hands
) and you're done.
