This is of course the reason that Microsoft has introduced these
requirements, so almost everyone will have to buy new hardware and the
hardware manufacturers are happy.
This also increases Microsoft revenue as new hardware means a new
Windows license, rather than some upgrade from Windows 10 which likely
would be free.

When you have older hardware and want to use it with a supported
browser, but do not want to fiddle with software yourself, you can
consider installing "CloudReady", the version of ChromeOS for generic
PC hardware (rather than ChromeBooks on which ChromeOS usually runs).
 
A free version can be downloaded from https://www.neverware.com/
 
It would run on Windows XP class hardware with sufficient RAM (2GB+).

Many, many are not.
The last XP browser update, of any ilk (I.E., Firefox, Chrome, Opera,
etc.), was a few years ago.

Of course, any discerning computer user would install linux or FreeBSD.
That should work for CPUs down to "W95 Class".

That would be the one.

I can see the hole for the metal speaker jack is not internally plated.
Go fuck your self.

and is there a wired connection to that connector terminal?
There is usually a terminal provided to allow for it by the
connctor's manufacturer.
 
Simple chassis contact is not something you'd count on for signsl,
power or safety, unless specifically designed for the purpose.
That's why the ground stud is labelled as such, and electrical
contact is made with reliable conductors.
 
I don't think face plates are expected to have any electrical
function - they're designed for ease of use and cosmetic values.
They can't be specifically listed as a conductor or insulator
in their safety files, unless they meet certain requirements.
Usually these stop at legibility after cleaning and flammability.
The metal or other surface they are mounted on serve the chassis
function.
 
Zinc/chromate passivation on steel was considered to be an excellent
conductive finish for purposes of emc control, when it was widely
in use. Current substitutes may have issues.

So don't use one.
 
Regular mains power is gonna be fine.
