I've had a MSI Trident functioning as a gaming/HTPC computer for years and the family loves it. They know how to browse the various streaming services and use Steam and Kodi.
This is diverging quite a bit from "a smart TV replacement". Especially if Steam is a requirement.
The gaming PC you have there is probably exactly the combination you want. But for most others it's the compromise to avoid I mentioned above. It delivers the console and TV/media center experience but with the full PC power consumption, noise, boot times, maintenance effort, and inconvenient controls.
The cheapest Trident I can find on eBay costs more (by 2-5x) than an Xbox and an Apple TV together. And these 2 deliver their respective experiences with far fewer compromises.

Knowing how to use it is just the bare minimum requirement. With an Apple TV for example you can do the same with almost instant startup time, 0 noise, 0 maintenance, ~1-2W streaming, and a small remote control. And probably has less ads than the average Windows computer :). I found the "right tool for the job" more appropriate for my use case but that might not work for everyone or all the time.
Things just happened that lead to that optimised state of using one device for alll (The MSI). Nevertheless the main question was about a nice 4k screen. :)
