Noiseless personal computer?

Hello! I began to assemble a computer from passively cooled components.
Theoretically, this task is as follows:
• Pick up is not much basking motherboard with a certain socket.
• With this socket you need to find (if one exists) processor which does not require active cooling.
• You also need to pay attention to other places of the cooling on the motherboard.
• Video card should not require active cooling.
• The most important thing is the power supply with the same characteristics. Such a power supply with the targeted search, I still unfortunately have not met (maybe someone knows is that possible?).
You can eliminate the option completely passive cooling, and to change these requirements on a cooler in the system but that it cooled and the CPU and power supply. That is, the power supply will be rebuilt. Mount to the power supply should also be considered. To think that there is need cooling?
Also the question arises, what characteristics will have the computer, what applications it can run? Interesting, in terms of software, a more modern requirements. This Is Microsoft Office. Browsers, no matter how be surprised, but some sites will not fully open due to its great functionality.

The second level of my search
Find/make "something" from the below mentioned parts of the device:
Is a nettop
- Notebook
Tablet (for Windows 7/8/10)
- Monoblock
...and any modifications to the architecture on which you are running Windows
Under something refers to several types of assemblies
1) The silent that-be to close a task 1 (above)
2) The smallest (mobile) (exclude the option to do this from the laptop – I don't know I just want to invent something great from it!!!, whether I'm just jealous of the companies that produce it. Know option laptop tablet (laptop with detachable keyboard) – but this path does not go
3) The cheapest (well, again, the processor is not heated). On this option I want a little more creativity but that's really not enough money if I have all the options sorted out
Well, my friends more tips. Can drive me into a dead end (like no one needs) but I will say I am ready for any variants of development, including financial (M. b to oust the current market with new products :)

Solution
Completely passive. Possible, why not? Expensive really needed very rarely. A couple of good fans ~500rpm to hear lot of hard work.

• Pick up is not much basking motherboard with a certain socket.

Heating modern motherboard can be neglected. Big size, little heating components. The South bridge does not emit much heat, the food chain - is still limited by the heat dissipation from a CPU, the large heat dissipation will not be there.

• With this socket you need to find (if one exists) processor which does not require active cooling.

Any, for which you will find sufficient exhaust heat of the cooler. And body. The case should not impede free air circulation. Top radiators cope even with the i7.

• Video card should not require active cooling.

Interesting, in terms of software, a more modern requirements. This Is Microsoft Office. Browsers, no matter how be surprised, but some sites will not fully open due to its great functionality.

What for you video card?

The most important thing is the power supply

Yes, this is the most difficult item in the first approximation. Namely passive blocks of the ATX can be counted on the fingers: https://forums.overclockers.ru/viewtopic.php?t=422392
But the second question is: why limit it to ATX? pico-PSU in the 150W is enough to power the system without a video card for the eyes. Processors with a modest TDP - hundreds of watts.
And the third point: if the PSU is cooler, it does not mean that he is rotating. At such low load more weighty list of power supply operates in the passive mode, despite the physical presence of the cooler. The list on the same link.

Not completely passive. To hear a couple of high-quality coolers in 500rpm - it must be out of town. Not in the city. To cool the ardor of any desktop 1-2 CPU coolers at 500rpm - no problem.
Much more expensive, but in principle any configuration, including a noticeable acceleration to gather ITS. (what to collect, the factory closed ITS garbage)

Well, after toying with a love triangle budget-performance-size
On account of the graphics card you are right. I was referring to the possibility of its presence (passive cooling), if it would improve the design. Thank You for the invaluable advice - brod commented on July 8th 19 at 16:42

Solution
And in what actually a problem? To build a silent system unit home? And what should he do?
Under task type Office - Inet - the Movie is more than enough for such a motherboard with a soldered processor and passive cooling (all included), SSDS and any BP with a disabled fan in a power load to warm it will not.
Or external power supply type laptop + Converter box.
The challenge in practical application? - the ability to carry a computer to work - brod commented on July 8th 19 at 16:44
