does this case contain a pick and pluck foam or a foam liner?
No pick and pluck foam, but it does have a molded liner.
It is supposed to come with pick-n-pluck foam but upon receiving mine it only had the thin foam liner with eight separate small foam squares. I placed those squares on the top and bottom of the case. It works really well that way. The laptop stays nice and snug now. If you don't use those foam squares, the laptop will slide around inside the case.
