My first gaming pc build (final stages)

 
Hey everybody i was just wandering if there would be any last minute improvements on my gaming pc. I want to overclock and play games at the highest quality i don't want an ssd and this website (https://www.pccasegear.com/index.php?main_page=index) is the only good pc part provider in Australia. I am totally confined to the parts and prices on this page. I want the price to stay reasonably around what it currently is and i already have a mouse :). So please feel free to leave a comment suggesting a different part or whatever! 
Thanks in advance!
 
p.s: this is my build:

Looks good. I would go with one of these monitors instead though:

Also, why would you not want to get an SSD?
