This video was created for students enrolled in my college PC Hardware class. The best way to determine the process for opening a case is to use the System Manual. But if it’s not available you can usually look at the case and figure out which buttons to push or screws to remove. This video provides a demonstration of determining how to open several different cases by first doing a visual inspection. The college class can be accessed at https://tonysako.com/home/pc-hardware/
