Lets assume the data on the HDD isn't worth the costs of a professional DR, and it's more of a DIY project.
Believe me, you're gonna waste your time and probably money too for nothing

after you're skilled enough doing it
which means, you've to have tools and a lot of practice, before even attempt the first successful inside parts replacement, on an actual real case.
