Just wondering if its worth taking my MacBook to a "Genius" for repair or are they going to say its my fault, warranty ends on the 17th March. I know there is a defect with the top casing cracking but not sure about the side casing. The MacBook has been sitting on my office desk for 6 months or so, lid closed during the night opened in the morning. There is also a smaller crack on the left hand side which isn't shown in the image below. And yes I'm well aware of other threads regarding MacBook cracks.
