Literally the only problem ive had with win10 is that the damn thing wont stay asleep. Other than that smooth sailing on a 3 year old self-build. Its not windows95 anymore.
On that note, i haven’t looked into it since i did my build, but a knowledgeable buddy of mine seems to think it can be cheaper these days to buy a built rig from a smaller builder than to source all the componemts yourself. Supposedly buying the components in bulk like they do more than makes up for the build premium. Something to look into anyway.
