This where you are going to learn how to build a pc and what each part does. all the parts you need is here

• Processor (CPU)
• Motherboard (MOBO)
• Graphic Card (GPU)
• Memory (RAM)
• Storage (SSD or HDD)
• Power Supply Unit (PSU)
• PC Case.
• Water-Cooling System

Processor (CPU): The central processing unit (CPU), also called a processor, is located inside the computer case on the motherboard. It is sometimes called the brain of the computer, and its job is to carry out commands. Whenever you press a key, click the mouse, or start an application, you’re sending instructions to the CPU.

Motherboard (MOBO): The motherboard is the backbone that ties the computer’s components together at one spot and allows them to talk to each other. Without it, none of the computer pieces, such as the CPU, GPU, or hard drive, could interact.

Graphic card (GPU): A Graphics Card is a piece of computer hardware that produces the image you see on a monitor. The Graphics Card is responsible for rendering an image to your monitor, it does this by converting data into a signal your monitor can understand.

Memory (RAM): Memory (DRAM) is a component in your computer that allows your system to perform many of its everyday tasks, such as load applications, browse the Web, edit a spreadsheet in Excel, or experience the realism of the latest game.

storage (SSD or HDD): Storage is another very important PC component. Your Hard Drive (HDD or SSD) is where you store your operating system, programs, and files. The most common types of storage are Solid State Disks (SSD’s) and Hard Disk Drives (HDD).

Power Supply Unit (PSU): A power supply unit (or PSU) converts mains AC to low-voltage regulated DC power for the internal components of a computer. Modern personal computers universally use switched-mode power supplies. Some power supplies have a manual switch for selecting input voltage, while others automatically adapt to the mains voltage.

you will also need a pc case make sure you have a good size of a case. so all your parts can fit inside o fit. and you will need a Water-Cooling system so your pc can cool down and prevent overheating.
