What's Inside Your Computer Tower (CPU box)?

The main parts of a computer cabinet are the processor, motherboard, hard drive, and power supply. The processor is the most important part of the cabinet, and the motherboard is the board that takes up most of the visible space inside the cabinet. The hard drive is the part of the computer that holds all your files, and the power supply is the part of the cabinet that supplies power to every single component within the cabinet. There are also other parts in the cabinet, such as a floppy drive into which you insert your CDs and DVDs, an expansion card, and many wires.
