Simple solutions
Get a mechanical hard disk drive and cheaper RAM (e.g. Kingston ValuRAM). Run a 32-bit OS so you only need 4Gb of RAM, max.
On-board video cards are getting better every year, unless you're a hardcore gamer, you don't need the latest and greatest from AMD or nVidia.
And if you're not a hardcore gamer, there's no need to splurge on a fancy 4K gaming monitor. There are very nice monitors for general/business use these days. And you can always pick up a refurbished monitor at a discounted price, especially those 4:3 or 5:4 monitors which are nearly extinct now because everyone has jumped onto the widescreen monitor bandwagon.
Caveat: Gartner has got things wrong before (e.g. "Windows Mobile will dominate the smartphone market!"), so take its prognostications with a pinch of salt.
