Open the case by prying on the edge with a suitable tool. I had to use a a opening pick to open the gap wide enough to be able to insert a flat screwdriver.

After inserting the screwdriver or a jimmy, bend the handle to the backside of the monitor. So that you lift the front bezel from the hooks and free it.

After opening two edges, be careful, since the panel and the logic board are only held in place by the closed case.

You probably will damage the case a bit during the process.
