We actually have a lot of shops, mostly small, that do their business
in Internet, they offer cheap low-end laptops (well, having 4GB of RAM
is low-end these days).

Dell has own line with Ubuntu pre-installed.

There is also an option to buy one of those Pis, especially Pi Zero,
which is €4/£4/$5.

And, of course, as long as they don't bundle Windows right into the
SSD/HDD (or do they?), assembling own machine is
the best way to get it working.
