What are the main components of a desktop computer?
user
Well, most desktop computers have a box that is called a case, and inside that box is a screen, keyboard and mouse, all connected to the motherboard which is a circuit board that has all the main parts that give the computer its memory, processing and storage power.
assistant
But the screen, keyboard and mouse are external components. I'm asking about what's inside the case.
user
OK, well inside the case is a motherboard, with all the main parts that give it memory, processing and storage power, and in addition, usually a processor chip.
assistant
Okay. What else is inside the case?
user
Then inside the case is usually a power supply, which transforms alternating current into direct current to power the circuitry in the computer.
assistant
Okay. And there are fans too, right?
user
Yes, fans and other cooling devices are common.
assistant
What other cooling devices?
user
On some computers you'll find water cooling systems.  And some desktop computers have cooling fans, which blow air over the circuits to help keep them cool.
