With all the crap and bloat in propriety brands, I'd never ever buy a pre-built PC, not in a million years....unless they paid me to trial it, of course.
The only pre-build I've had was a beautiful black beast from IBM, no extras or bloatware, just the OS and proggies I needed/wanted. However, my needs outgrew it and my next machine was a custom build from my fav puter shop which, I'm happy to say, for my/our next PC, is about 800 meters from my front door.
My third and current machine is one I built and have constantly upgraded myself...and, touch wood, it has not caused me any hardware related issues at all. I also built and upgraded my wife's machine, which has been trouble free and still runs after a year in use...not bad for somebody who'd never even operated a computer before 2003, much less seen the innards of one to know what went where.
Although I can do it myself, my hands don't work so well these days, and my/our next machine(s) will be custom built by our fav techie, who charges us no extra for labor when he supplies the parts.
