Take pair of pliers, bust off top corners of slab. Jam flathead screw driver into where flip is, watch your fingers! Rotate 90 degrees until you here a popping sound. Insert flathead further into slab, rotating to pop more. Once the case is fully breached, drag tip of flathead down each side. You'll get through two or two and a half sides and the entire thing should pop out. I've done this method on many, many dozens of cases.
