The case bulged open. I popped open a crack about 3-4mm high along the seam of the case (in case the photo isn't visible). The horrible grinding sound went away, and the machine seemingly boots and runs ok in spite of the new deformity.
1) Given that it's out of warranty and that the case itself has been affected, is it impossible to fix at any price?
2) If I can't get it fixed, is it safe to keep using it?
