These are the parts for the PC i intend to built:
AMD FX 8320
ASUS M5A97 EVO R.20
SAPPHIRE TOXIC R9 280X (found it cheap on Amazon)
Corsair 8gb (2x4) Memory
Zalman Z9
Corsair cx750
1tb WD blue
Coolermaster hyper 212 evo
Can anyone recommend some improvements to optimise for gaming and does will the Graphics card fit in my case.
i haven't picked any peripherals yet or a monitor, you can recommend one too please.
Build looks good, but What is your total budget?
The Zalman Z9 case has a max space for graphics cards up to 290mm long. The Sapphire Toxic R9-280X is 308mm long. So unless it has a removable storage tray, no, it won't fit.

... and I'm not a huge fan of Corsair CX series PSUs... look for XFX, Seasonic, or upgrade to the TX line at least
Any suggestions for a case which is larger than the Zalman z9 but similarly priced
It's a good build. Very appropriate. The only concerns that I have (and share with the above posts) is the case and the power supply. Never been a big fan of the CX series. You'd be better suited with a cheaper XFX 550W. That should grant you a little bit of money to allocate to a higher quality chassis.
Case at similar price of the Z9 > Bitfenix Shinobi or Comrade. Also the NZXT H230 (my pick).
