So I’ve been looking at upgrading my PC and it looks like I can get a better “micro” pc than my current (ancient) desktop for significantly less money than a full blown gaming rig. An example of such a rig is this.
I don’t have high gaming requirements - I play mostly old games, I think the newest games I play are from 5+ years ago.
What reasons are there for not buying one of these (over a comparable “proper” desktop)?
It’s not a “gaming pc”. What you are asking is why shouldn’t you just use a small basic pc to play old games instead of buying a gaming pc.
“Why should I get a PS5 when I can get a PS2 for way cheaper?” Is essentially your question.
