I understand where you’re coming from, but there are some flaws with your reasoning:
- About Kernel anti-cheats: if you wish, you can dual-boot Windows and any GNU+Linux distro, without any issues.
- The LibreOffice thing: there is OnlyOffice, and even M$ Office has Open Document format compatibility.
That hardware is very powerful, so Linux Mint (maybe Debian Edition) will do the trick.
