[0003] Currently, when components inside the host case such as the graphics card and memory module are damaged during use, maintenance personnel need to disassemble the computer host case shell. However, the case body and the case door of the existing computer case are fixed together by bolts. Therefore, during the disassembly and maintenance process, external tools are needed to disassemble them one by one before maintenance, which reduces the efficiency of case disassembly and maintenance. For this reason, we propose a computer case that is convenient to open and close. Content of the Utility Model

[0004] The purpose of the utility model is to provide a computer case that is convenient to open and close, which has the advantage of being convenient to open and close, and solves the problem that the case body and the case door of the existing computer case are fixed together by bolts. Therefore, during the disassembly and maintenance process, external tools are needed to disassemble them one by one before maintenance, which reduces the efficiency of case disassembly and maintenance.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A computer case that is convenient to open and close, including a case body. Positioning sunk grooves are opened on both the front and rear sides of the case body. A case cover is arranged inside the positioning sunk grooves. A handle is fixedly installed at the upper end of the side of the case cover away from the positioning sunk groove.
