The IBM PC in 1981 cost $4,500 to $8,500 in today's money. The original Mac would cost $6,000 if released today. Computers have become a great deal cheaper in the ensuing decades.
Bill Machrone, long-time editor of PC Magazine, coined a "law" that the computer you wanted always cost $5,000. Which held reasonably true for a rather long time. It broke down maybe about 10 years ago although, as with the latest Mac, you can still get to $5K without too many gymnastics for pro video work or high end gaming.
You can configure a desktop for way cheaper than that and it can run 90% of modern games. Just don't get the latest generation top of the line Nvidia/AMD card, either get the previous top of the line one or a decent mid-range one (check benchmarks when choosing).
Don't get the most expensive RAM or CPU, you lose 10% real performance but you halve your budget.
Windows is fantastically supported: Microsoft Office, Adobe suite, AAA games, Active Directory, databases, browser and browser plugins, and a thousand others.
When I was in college in the mid 2000s my senior project needed a single board computer. We spent $500 on a small PC104 board with a 100MHz National Instruments Geode (x86 compatible) process. That didn't include any RAM or storage. I really wish the Raspberry PI would have been available back then. Especially the Raspberry PI ecosystem, makes interfacing with stuff so much easier. We interfaced a small LCD I found at a surplus shop and it took us weeks to get it working. No you can buy a touch screen LCD for $30 and there are libraries to get it working in about 20 minutes.

By the way, it turns out people think "automation is replacing jobs in manufacturing" because they've misread the data showing them just how much cheaper computers have gotten since then, and therefore how much more computer one factory employee can make.
