A typical basic CPU in order to function will have: a case; 120/240V power supply; motherboard with processor and RAM slots; hard drive; external media device (CD-ROM drive, floppy drive, etc); ports for i/o devices (printer, keyboard, etc); and a video card.

Most CPU's have expansion slots on the motherboard for sound cards, network cards, modems, SCSI interfaces and other cards. They may also include multiple drive bays for hard drives, floppy drives, DVD-ROM burners, USB ports, or advanced video and sound inputs and outputs. Fans and coolant may be used to dissapate heat.
