I would get a cheaper case. My PC case was 15$. I also have very good cable management.
I don't see the point in spending more than 25-50$ on a PC case let alone 160$.
There are some good 20.1-inch LCD wide screens out there for about the same price as that 19-inch; My 20.1 wide screen is much lager than my Father’s 19 inch square screen.
Heres a PIC of what you can do with a cheap 15$ case. This was back when I still has my 4200+ buts its still the same just different MOBO/CPU.
