Upgrading Computer - £150-£200

[luke.johno.91]

Hi everyone,
I was looking at upgrading my computer and I was hoping to keep some of my original parts:

Intel Core 2 Quad Q8200
Radeon HD 7750
HDD 600gb
Packard Bell iMedia x2416 case

I was looking for a new:
Motherboard
PSU
8gb RAM

I was also going to get an OCZ Vertex 3 120gb and Windows 7 64bit.

Would I need a new CPU or can I keep my current?
Can I re use my old case?

Thanks guys

Luke
