PC Case Repair
The PC case is simply the housing that the computer's components are installed into. Cases come in a variety of sizes and shapes suited to both where they will be used and to house all of the required components for a particular PC.
The case sometimes has a built-in power supply, and if that power supply fails, the entire case must be replaced. Other reasons to replace a case are for PC upgrades, switching to a more convenient size or style and for aesthetic reasons.
