I would get a Lenovo Thinkpad. They are pretty damn solid.
They happen to be having a sale:

Very durable laptop with a thick, hard plastic case. The screen is the most solid I've seen in any laptop (outside of a toughbook). It has to be a thinkpad though. I have an Ideapad too, and it's very flimsy in comparison.
