Leaving one fastening screw still done up in the corner and then attempting to wrench off the case may cause significant damage to the metalwork, but this is generally easily bent back into shape and not very expensive to replace. You can do better.Fortunately, there is a plethora of computer case designs, and a gratifying number are fiendishly difficult to take apart and, especially, reassemble. To maximise the chance of damage, ignore any locking tabs and slots, don't worry about pinching cables in the case, and make sure you push really hard.
When replacing screws, remember to tighten everything as if the computer were a major structural component of the Sydney Harbour Bridge. Overtightening screws increases the chance of reaming the heads, and the extra frustration involved in removing super-tight screws increases the chance that someone will give up and turn the machine over to a professional. Use of an electric screwdriver makes screw destruction easy for anyone.
