The Motherboard i think or maybe the processor.
As far as I know the graphics card is the most expensive part of the computer.
After that is the processor
super computer
People are NOT considered the most important part in a computer system. People are actually the least important and tend to cause the most problems in computer systems, by accessing parts of the Internet that causes the computers to be compromised, by inserting USB Drives unknowing infecting them with viruses, and messing with the system files causing system crashes and loss of data.
The computer component that presents the most risk of electric shock is the power supply. Since there are large capacitors in the power supply, it is possible that you might get shocked, even with the power supply unplugged.Another component that presents a shock risk is an internal modem. You might grab a hold of it while there is an incoming phone call, and then get shocked from the ringer current.

Yes the CPU (aka microprocessor or Central Processing Unit) is the most important, but it is not necessarily the most expensive.
The single most expensive component of a system built from separate components is generally the processor.

A laptop if you want a complete computer that you can carry around (there is a CPU in a laptop)A CPU if you have a computer and want to upgrade or replace the "Central Processing Unit" which is the most expensive and complicated component.
While it's hard to define one "most important" part, I'd have to say that the power supply should have that distinction. Without electricity flowing to the computer, the rest of the electrical system has no purpose.
There are no records for the most expensive computer desk in the world. A computer desk price or value can be very expensive if it is a custom made piece of luxury furniture.
The most expensive computer is made in Japan. It is an Earth simulator costing over $400,000,000, which makes it the most expensive computer ever built.This very expensive computer is used for a variety of international projects. Most are related to atmospheric, climate, and oceanographic simulation.
