Whenever you mount a CD-ROM drive, a harddisk or a floppy drive, be sure to use the wrong type of screw; use the small ones for the harddisk and the big ones for the CD-ROM and floppy drive. Applying excessive force when mounting these peripherals again is a big plus, but keep in mind that for maximum effect they should actually not be fastened securely and must NOT be mounted with more than one screw. If you're constantly moving your case around, then try NOT to do so in a careful manner, but rather jerk it around. Dropping it on a concrete floor from an adequate height of course is a great way to test overall structural integrity, and maximum effect is attained with ill-fastened peripherals. The effects of a harddisk or any other heavy peripheral crashing around inside your case are not to be sneered at, especially with the computer switched on.



Fig 3. Mounting the motherboard, notice the correct orientation of the copper standoffs.
Furthermore, when mounting a motherboard, be sure to use all supplied copper standoffs and place them in a random location, then, contrary to the peripherals, fasten the screws holding the motherboard down as securely as possible. Mis-aligning the motherboard, if at all feasible, is a great way to inflict further damage. The reason for mounting the motherboard securely is two-fold, first off we want the motherboard to be as rigid as possible as to raise our chances of inflicting damage on add-in cards. Secondly we want the randomly placed copper standoffs to make maximum contact with any motherboard pins underneat, increasing the chance of a motherboard short-circuit.
