I currently own a 430 and use to own a 300.
300 - better build construction(thicker steel),bad cable management(use holesaw or dremel)=easy fix,high quality fans(quiet on low).
430 - better cable management,only one included fan,the case is chopped off at top(short)
The Illusion is a steal at that price and a better case overall=no brainer
Yeah it seems everybody complains about the 300's bad cable management, but just like you said, it's a quick fix.
Thanks for your helping out.
