Shapes and Sizes

PC cases comes in different shapes and sizes called the form factor of the case. The driving force behind these forms factors are the motherboard.

You cannot, for instance, build an AT form factor motherboard in an ATX (Advanced Technology Extended) case. The connectors at the back would not fit correctly in their slots.

Layout

The layout of a PC case is fairly straight forward. The motherboard is screwed to the chassis at the bottom if the case lies on it side.

The power supply is usually at the top when the case is upright and has power cables that connects to the motherboard.

Then there's drive bays at the front with screw holes to fasten the disks with.

You have buttons and LEDs(Light emitting Diodes ) in the front outside of the case.You can use these to switch the PC on and off and get visual feedback of your components via the LEDs.
