Not too long ago I had to rebuild my main desktop since it generally broke down after about a decade; an old stock machine I put an SSD, video card, extra RAM, and replacement disc drive in before later installing Linux Mint when Windows 8.1 went out of service. That went fairly easily once I figured out the right motherboard form factor to reuse the case and the optical drive as well as leaving room for the video card, replacing everything else inside with relatively budget parts and making it into a purely Linux Mint machine, with a performance boost just from how the current lower end had since shifted upward.
The question now is what would I be doing with my Windows 10 gaming machine come next October. Just working out a couple options. There's the pessimistic version where I begrudgingly install 11 and have to spend a bit of time configuring all the annoyances out of it and hope the current version coin flip favors games not being laggy, or the optimistic one where I can get stuff like VR running pretty well on some dual-booted Linux distro, perhaps SteamOS or similar, without more than usual hassle, even if I have to get a better graphics card for driver performance overhead reasons. Rebuilding the other machine did result in the gaming PC getting a higher capacity power supply during some other troubleshooting, so there's some limited flex room, though ideally it's not a necessity. I'd just rather have all the computing power go toward what I want like any other machine, not some weird "AI" screen recorder module I won't bother with for example.
