I built this rig as my first gaming build more than a year ago. At the time, it was about $1,500 (AUD). I have had no troubles with this build and it played any game smoothly. I found this to be a great beginning build and highly recommend to others who are looking to start at a relatively cheap-ish price (in Australia anyway).
The case was quite small and didn't leave much room for cable management but as a first time builder, I wasn't too worried about it. I added more fans because I liked the blue colour in my case.
This rig was running windows 8.1 and as I said before, had no issues performing tasks and running games smoothly. If you plan on running extreme processors/games, I would suggest a better CPU and more RAM + an SSD to store the OS on. This'll speed up the rig but as a beginning build, I was very happy with this.
The keyboard is rather flat so keep that in mind when ordering it.
By the end of this rig, I found that I wanted more speed and processing power. Check out my other projects to find out what I have and what I am aiming to build.
