They can perform numerical calculations, logical calculations, and have storage and memory functions. They are modern intelligent electronic devices that can run according to programs and automatically and quickly process massive amounts of data. Most of the computer components are installed inside the chassis.

[0003] Most of the existing computer cases have a side panel installed on the side. When the internal components of the case need to be repaired, the side panel of the case needs to be removed, and then the internal components of the case need to be disassembled and repaired. Since the panels on the other sides of the case are not convenient to remove, the space for people to disassemble and install the internal components of the case is small, which makes it difficult to disassemble and install the internal components of the case. In addition, when the internal components of the computer case are damaged, people usually move the case to a corresponding repair shop for professional repair personnel to repair it. The existing case is not convenient to move on the ground, and people can only carry the case, which increases the difficulty of people carrying the case and reduces its practicality.
