It depends what the question is. I built one a few years ago from a basic small form factor box with motherboard. I just had to add processor, memory, HDD, video and network card. All in all quite a simple process.

The one detail I did learn was simple: work out how much power all the bits are going to take and add 25%. Then buy the next size up PSU ...
It's surprising how much power a good CPU and GPU can take: a top end GPU can be around 400W peak - which means you will probably need a 800W PSU or more once you figure in the processor, ram, drives, and USB peripherals.

Personally unless he really needs the PC I'd wait until GPU prices come down. Although you can get them now they are grossly over priced.

I had to try the drops for several weeks, but I got my Radeon 6900 xt at AMD shop prices (around 990€).

Good deal!

10 weeks trying. Every Thursday there was a drop around 300 units, sometimes out of stock again within seconds.

I've been doing the same with the GeForce 3080, although they are available they are $1000 over the price they were before pandemic. I'll wait!

Unless you're building a PC for extreme gaming, buying a GPU card that draws 400W is completely crazy. (Well, persponally I think it is crazy even if your primary activity is gaming.)
For most of what I understand by "desktop" use, the built-in GPU in the latest CPU chips is probably more than enough. My main computer is equipped with a display card released more than nine years ago (a GeForce GTX 660 Ti) - I am sure that the integrated GPU in today's CPUs will run in circles around it. Yet I feel no real need for anything faster. But then: I don't play computer games at all. I edit digital HD videos. I play around with SketchUp; the model of my house and garden has 8.8 million edges and 4.2 million faces - that is the one single application where I notice any lagging in the graphics part, but it is tolerable.
Sometimes I challenge extreme-PC owners to show me how their 64 GByte of RAM is filled up, their 12 cores run up to 100%, their Gbps fiber connection runs at full speed and the disk channel is saturated. They always fail miserably, even when making serious attempts on loading sixteen hugge applications and skipping like crazy from one to the other in an attempt to run into some saturation point somewhere. An extreme gamer may be capable of saturating his GPU (because the software is designed to utilize all GPU power available!), but the rest of the system has plenty of capacity. Regardless of any realistic desktop application mix.
Some people brag with their cars. Others with their jewels. Some with their PCs. And they laugh at my nine years old GPU. Let them laugh - it satisfies my needs!

I also have a GTX660Ti - because the onboard graphics are 1) slow, even for Windows, and 2) only support one monitor. My 660 supports 3 (and plays GTA V as a nice bonus)
Even that requires 250W peak current, which means a 450W PSU is really the minimum. As I found out when my 250W just couldn't cope ... sometimes.

Some people just enjoy a high performing PC. It's not something meant to "brag" or put anybody else down. Sounds like somebody is feeling just a little inadequate.
The difficult we do right away...
...the impossible takes slightly longer.

I had built my last four computers but video cards cost too much these days and I couldn't find the one I wanted in stock for a decent price. For these reasons, I bought my last one. It has a 3090 GPU and a liquid cooled set up. The other day I wanted to find out what it would cost today and I found that because of some new laws that went into effect on 1 July I can no longer buy this computer where I live because it draws too much power at 1000W. I got it about one month before the law took effect. Similar laws are now in effect in six states of the USA.

We had the same thing here with vacuum cleaners - EU law reduced the max power to 1600W then to 900W, probably to make rechargeable ones competitive, despite the major effect being they just don't suck as well.
I've still got my 1900W, which actually copes with cat hair!
Lawmakers don't care if their changes mean that something just doesn't work any more, just that it fits their agenda (or more likely the agenda of whoever paid them most to adopt it).

A good CPU draws only a 6mA (max, according to the data sheet, only 3mA on average) operating current. 30mW (15mW on average) wenn running at full blast. What a battery life if you use it in a mobile device, but go easy on the LEDs. Every single one needs more power than the processor.
I have lived with several Zen masters - all of them were cats.

Fortunately you don't have to benchmark the performance when you are putting together the hardware. You just have to provide enough power to meet the worst case, all components at max power all at once. Plus a little tolerance. What you get for that power is the next question, after you have it running.
But you know which little old processor I was talking about. A small wonder for its time and if it was built with a more modern CMOS process, it would probably draw only a few µA. But it is a completely static design, so there is no minimum clock frequency. So I can effectively put it into standby by completely stopping the clock and lowering the supply voltage to a minimum. Then only a tiny leakage current will remain. The memory can be powered down in a similar way and retain its contents, everything else will be shut down completely. Such old devices can be really practical in portable devices.

I doubt very much that you are talking about a CPU that can run Windows at any useful level of performance (or, say, the Eclipse IDE if you are a Linux guy),
For an ARM based SoC, aimed at embedded / IoT applications, you are certainly right - and you get them at significantly lower power consumption, too. Take a look at nRF5340[^] - a dual-core chip. The network core draws less than 2.5 mA when running; it may be 'on' but idling, consuming just 1.7 μA, ready to jump up more or less immediately whenever something requires its attention.
The chip can't run Windows, though. Not even the ARM version of Windows.

Embedded? You might call it that. I was talking about a very old processor that was used in space probes, among other things. It had a reputation for being very modest in its requirements and surviving in places where other processers of the time simply died, like in Jupiter's radiation belt. No, it can't run Windows, thank god.

You didn't identify the CPU architecture or model. I guess it wasn't an x86 Was it a specially designed, one-of-a-kind? (or possibly a-dozen-or-thereabouts-of-a-kind) Or was it a generally available CPU? How old is 'very old'? So old that it was built from discrete components? (I'd be very impressed if you can build a CPU from discrete components,drawing only 6 mA!)

It's ferst incarnation was called FRED and was indeed built frpm discrete components around 1972. Then came FRED II[^] in 1974 as a prototoype with the two chip CDP1801 processor. And then, in 1976 we got the CDP1802, one of the earliest CMOS and RISC processors.
And that little guy flew to Jupiter in the Galileo space probe[^].
