It's another one of those weird non-metric units. In the world of air conditioning (or cooling in general), a "ton" is the amount of cooling you'd get from melting a ton (a short ton - that is 2000 pounds) of ice that's already near its melting point. Air conditioners are usually rated in tons per day, with 1-5 tons about right for a typical apartment or house, depending on things like square footage and climate.

It'll probably end up worse than that. Turn off secure boot and Windows may still run, but it will no longer verify and all these sites will now refuse to work on your computer. So if you like to run Linux, even dual booting or running Windows in a VM for those things that absolutely require Windows won't be good enough anymore.
The issue seems to be that the build-it-yourself market caters almost exclusively now to the gaming crowd. If you want a gaming PC then you can still get a good deal building it yourself, but if you just want an inexpensive computer it's going to be tough to beat a prebuilt.
The last time I built a PC for myself was 2012 and I've been looking at replacing it. I have to say the state of the DIY market today compared to 10 years ago was a bit surprising.
Next year should be 100% Linux for me. Steam is dropping support for Windows 7 at the end of this year, and I don't have any other newer Windows PC to run Steam on.
