What should I upgrade in my PC?

I have $240 to spend on upgrading my PC. What I plan to do is to swap my current case, an NZXT Phantom, for a nice small and minimalistic Fractal Design Define R4. The reason for this is that the Phantom is a bit too big for me and looks a bit dirty? compared to some other cases I've worked with. Secondy, I plan to get a Corsair H60 in the place of an NZXT Havik 140. I know this is a downgrade in terms of performance, but I do not like how crowded the case feels with a giant air cooler. Lstly, I would like to get a boot SSD to speed some things up.

My current Specs:

CPU: Intel Core i5 3570k @4.2 GHz

Cooler: NZXT Havik

HDD: Seagate 2TB 7200RPM

MoBo: ASrock Z77 Extreme 4

PSU: Corsair GS700

Case: NZXT Phantom Black/Green


I recommend keeping your case for now and get This or if you really want a new case This.
