I'm selling this because I don't need it anymore and would like money. So that there are no secrets, here are the two issues which might be hard to tell from the photos:- The lock for the optical drive is missing, so if someone shakes the computer very hard, they could make the optical drive fall out.
- The lid lock is a little loose
