My first PC was a Dell and I really can't complain too much. My speakers broke, I got new ones within a few days replaced free, my modem caused havoc and the guy spent hours and hours and hours on the phone with me getting it fixed.
I remember getting off the phone after just taking my whole PC apart over the phone, which I'd never done before, and thinking this is stupid I just spent $3000 for something I could have built. So I did the next time.
The issue I had with Dell was that when it came time to upgrade they had made it so difficult. What possible motivation they could have for having proprietary parts I do not know. Only a moron would get to the point where they know they need a new PSU and still shell out the Dell premium for it. So I just pushed that PC to the side and built a new one. I was kinda disgruntled with the fact that I couldn't upgrade that machine after spending so much on it.
