Basically just the CPU fan, case, and PSU (if you're lucky). If someone can figure out how to get Doom running on just those 3 things, young people will be able to ascend.
It was a joke I assumed you'd be okay with given your username, which signalled an appreciation of self deprecating humor :)
To be frank, I didn't think you were friendly enough in previous comment that I wanted to engage with you, but I had something useful to say. So I referred to your username as hook for the other discussion. I think the person I responded to did a good job explaining why the PWM comment was technically correct, so I had nothing to add to that.
But other than the comment you made I thought could have been friendlier, I have nothing against you. I'm not making any inferences about you as a person based on one comment. I dont actually you're stupid, you're still the stranger on the internet you were before.
