Could also be selective memory. "I can't recall having any hardware related issues since, oh, 2005 or so" --> oh, that issue? Yes, of course I had that, everybody has that, that's par for the course...
The last time I attempted was 2017/18. Pretty plain clone PC desktop - MSI motherboard, ryzen 1600, AMD Radeon 580, etc. I bought a couple a different WiFi dongles to make sure the chipset was supported.
Yet the problems remained. Maybe when people say they had lots of problems and it wasn’t worth their time, take them at their word ?
And LTE modems. And sleep and suspend. Oh there is also this bug with screen locking that shows your desktop for few seconds. Oh and with dual graphic chipsets too.
Parent must be very unlucky, or in fact not realise it is their tweaking and tuning that causes issues.
