That's really all up to you man. I mean if you want to know what we see as a better PC is kind of you asking us for attention but if you want our acceptance as an awesome! gaming PC then you will have to probably spend some more money. Everyone is different though with their builds and opinions.
As for me, I would say add some sleeving. A PSU cover and some LEDs and maybe some more colors, I don't know what but something. Other than that like I said, it's very clean and neat [that's a good thing]
It's still a good build to me.
