Ok guys, i already have an i5-2500K and an mATX P67 mobo (from about 2 years ago).

I have sourced a really cheap 7770 (£40~ !!) and am more than happy with the performance of the 7770.

and am looking to upgrade my case, ram, PSU, HDD and optical drive.

I would like it to be small, so it'd be an mATX build.

Overclocking? Not really, but i have the option if i need it with my P67 mobo.
SLI/Crossfire? No, my mobo doesnt support it anyway.

I am a student, so need pretty much the cheapest stuff really :p

Looking through this is the cheapest i could find:

Is there any real gaming performance advantage with 1333Mhz and 1600Mhz ram?

my budget is under £170, but if you know a cool mATX case then that would be useful :)

Thanks for your help in advance.
 
Solution
Look at the NZXT vulcan. That case you have there isn't great. Get 1600mhz RAM, it costs like 1 pound more. No reason not to get it.

I have an NZXT vulcan and I love it. best airflow in an mATX case and alot of space for the size.
