A server container includes a main body, at least one support plate, at least one angle detecting module, and an alarm module. The main body includes two opposite sidewalls. Two opposite edges of each support plate is interconnected the two sidewalls. Each angle detecting module includes an angle sensor and a controlling module. The angle sensor is correspondingly positioned on one support plate and for detecting a bending angle of the support plate and generating an angle signal corresponding to the bending angle. The controlling module is configured for comparing the voltage of the angle signal with a reference voltage which corresponds to a predetermined degree and generating a control signal upon a condition that the voltage of the angle signal is greater than the reference voltage. The alarm module is configured for generating an alarm upon a condition of receiving the control signal.
