Just had to do this myself. Remove the cover where the stand joins the back of the monitor, this is quite easy to do with your hands and without tools. There are six screws which hold the stand bracket to the back of the case, remove the two screw on the bottom of the bracket on the far left and right. Start at the slot on the bottom of the case and insert a large flat screwdriver, the case can be prised open without causing too much damage. Hope this helps.
