Question

How do you make a computer

Answer 1

To make a computer you would need a few resources first which include a motherboard and possibly some peripheral device connectors (USB plugs for example so you could connect a keyboard and a mouse if you wanted to). Then, you would need some sort of screen on which you could view the code required to run a simple version of a computer operating system. 

All of this is needed to constitute a basic computer. 

Answer 2

You need a system case, motherboard w/ a processor that's compatible, hard drive, RAM sticks, a power supply that will be able to give enough power to everything, an operating system (Windows, Linux, etc.), and a monitor. Then you need to make sure you have all of the extras that you'll use, such as an optical drive, mouse, keyboard, etc. Not to mention you need the right cables for everything such as ATA (ribbon cables) or SATA cables.
