How can I learn to build my own computer with Arm processors?

My question is about build a computer without SoC ICs and FPGAs. Is it possible? how?

I know it used to be possible with Arm Classic cores; ie up to Arm11. Some of the CPUs were "simplistic"; as in they contained only the Arm core and very little memory, anything required for a bootloader, but more memory required external DDR. With newer technology, Arm SoCs became widespread, and to be honest, I don't know of many chips that don't include most of the controllers. Granted, some chips will require external DDR and NAND, but not much else. If you are thinking of the Good Old Days (c) where you needed a CPU, memory, memory controller, interrupt controller, serial controller and indeed *.* controller, I don't know of anything. Besides, most chips will use SMT, making it hard for enthusiasts. With the exception of Cortex-M chips, I've never heard of a DIP chip. You might want to try with an Arm926EJ-S or Arm1176, but in a way, it is a shame not to make the most of recent developments; the Cortex range really is worth it.

Thanks a lot James.

I could understand you say new Arm processors have some peripherals built-in and they are SoC? If it's true what is the differences between a Arm products and other companies such NXP that use Arm processors to provide a microcontroller based on Arm? Can we buy an Arm processor and build own microcontrollet instead of buying from NXP or others? Is it very hard,expensive and impossible or it's easy and inexpensive?

I want to build a mini-PC like Raspbbery PI by using Arm processors, according to my needs. How can I do it?

Arm don't sell any actual physical processors (well except for some high end development boards). They sell intellectual property, they enable others to build a system on a chip easily with what they are interested in. In the past one could get a processor and some memory and and some other chips and stick them on a circuit board probably with one's own FPGA to do what one wanted. Today most of that can be stuck onto a single chip, instead of a physical chips to stick on a board one licences IP and fits it into a SoC, the board it is put on is there mostly to provide human sized sockets.
