I used to use Gentoo on my laptop, mostly for fun but also because I kept having issues on other distros (Ubuntu mostly) where I wanted to run the latest blender release but my libraries were out of date. On Gentoo I could easily get the most recent builds.





Totally possible.
I recommend making room on your drive using windows tools to shrink the windows partition before letting your Linux installer add new ones, or doing it manually. This is just so that no weird filesystem bugs show up after resizing your ntfs filesystem with Linux tools. Never had a problem with them but it’s probably good to use Microsoft tools to mess with the Microsoft filesystem just in case.
