I've done some research on my 2007 MPB and it turns out I have to really take it apart just to install a new Hard Drive. My question is, is it worth doing it by myself?(Is it easy enough to do it by myself?) Because there's a local company that has a guy who knows how to upgrade apple computers and notebooks but it'll cost $75 for him to put in the new HDD which I think is way to damn much. So is it safe(as in I have small chance of breaking the MBP) to take apart? Is it easy to take it apart? Or is it worth the money to have someone else do it?
