Abstract: A method of integrating a personal computer casing with a monitor body is disclosed. The method includes providing the computer casing with a top open end, providing the monitor body with a bottom wall configured to cover the top open end and having a leg portion protruding downward from the bottom of a front screen portion of the monitor, providing a first pivotal unit on the leg portion and a second pivotal unit on a front end of the computer casing, engaging the second pivotal unit with the first pivotal unit when the top open end of the computer casing is at a position away from the bottom wall, and subsequently turning the computer casing about the first pivotal unit to place the top open end against the bottom wall so that the top open end is covered by the bottom wall of the monitor.
