Microsoft increased prices for all of its Surface PCs this week, with most models priced hundreds of dollars higher than they were when launching. Windows Central highlighted the increases, which now see Microsoft's mid-range models priced above $1,000 and flagship models priced starting at $1,500. A Microsoft spokesperson said the price increase was due to "recent increases in memory and component costs".

Since you have a fair number of boxes to manage. If it was me, I would take a look at Atomic distros. And Fedora is a big driver of them. Since you like KDE, you could test the Kinonite spin. And if you do want the hassle of installing nVidia drivers, then maybe Aurora, (a direct fork of Kinonite), might be a better choice. You can choose your graphics card when you download the iso, install and then have everything working on first boot. Aurora also has all the codecs included. Atomic spins make managing multiple computers for users so much easier. Your partner can install/uninstall user software with little worry about breaking the system. And you sleep better at night.
Not saying you need to do it, go have some fun with CachyOS and other distros. But maybe start learning about it and thinking if it might have a place for you.
