Modern hardware from a PC to an old laptop, perhaps?

Question

Iron

Hello everybody.
There is an old laptop - Fujitsu Siemens xa2528, 2008. The stock contains amd turion tl-64, antediluvian 65nm, and nvidia 8600m.
The disease of these laptops is overheating and failure of the video chip, which costs 7k rubles, which makes its repair unprofitable.
Question:
Does life have an idea to shove a mini atx motherboard into it, coupled with a ryzen 2200g or i3 cofee lake + version without a cooler of some kind of nvidia 1030, 1050.
Is it possible to attach monitor and keyboard cables to new hardware, how strong will the problem with proprietary drivers? The question of space is not worth it, the laptop is 2 times thicker than any modern one.
The relevance of the issue is primarily in the price, new laptops up to 20k are quiet horror, this laptop has an excellent matrix, 17", good audio, with a mini subwoofer at the bottom. And as for the performance of new laptops on celeron, this is quiet horror, it would seem 14nm and other modern goodies should have made them excellent budget solutions, but even watching streaming video in 720p is a whole epic, it is not possible to endure, and this is why such a question has matured.

Answer 1

In short - you're confused.
Then not miniATX, but microATX. And ITX is better - mini, nano, pico ... There, at least, the LVDS bus is more common. Google for words mini ITX LVDS.
For one, you will see that very often laptop components are used on such a form factor, and such nurses are installed in all sorts of monoblocks and "thin clients".
Just an example
With a keyboard connector, it's a problem, it's easier to find an ordinary, but thin keyboard, you can even immediately with a touchpad.
In general, this is quite a serious modding.
