This is a bit tricky, but not impossible.
1. Remove the two visible screws near the bottom. 2. Pull the plastic covers off the stand: Pull from the inside (nearest where the stand is attached to the monitor. 3. Undo the screws and remove the bracket. 4. Under the bracket is the final screw. 5. Try pulling the front off the back starting at the bottom. It'll require a little force. 6. Now you should be able to get a knife in to pull the rest of the case off. Leaver by pushing the front outwards and back inwards and the clips should come off ok.
