Hey
good to see somebody using the outline to give us the information.
I also live in Australia, and don't worry there's some good shops around here.
so it would help if you told me in which state you live:
VIC:
www.pccasegear.com
QLD:
www.umart.com.au OR
www.msy.com.au
I personally used MSY and had no issues with them.
not sure about the other states, sorry.
anyway, since you have a decent budget I'm sure we can find something right for you. I'll just throw together a quick list for you then.
Case option 1: Corsair Carbide 400r - $118
(this is more on the classy/sleek design side. I have one of these myself and can say it's a great case)
Case option 2: Coolermaster CM-690 II windowed edition - $119
(this is more on the showy/LED's/windowed design side)
CPU: intel i5 3570 - $219
(since you aren't planning to overclock)
CPU Cooler: Coolermaster Hyper 212 EVO - $36
(It's always good to have an aftermarket cooler. Quieter, better temps, aesthetics, and prolonged CPU life)
Graphics card: Gigabyte GTX 560Ti OC'ed edition- $249
(this thing is damn powerful, should handle all modern games with ease.)
SSD: Samsung 830 64GB - $79
(OPTIONAL- but would be a nice addition to your build, will make loading things much faster)
HDD: Seagate Barracuda 500GB - $69
(for storage. not sure how much space you need so went with cheaper option for now)
Memory: Corsair CMX 8GB (2x4GB 1600MHz) - $59
(more than enough RAM for gaming/general use)
Motherboard: Gigabyte GA-Z77-D3H - $135
(nice solid motherboard)
Optical Drive: Samsung SH-222BB SATA drive - $22
(not much to say. It reads and writes just fine.)
Power Supply: Seasonic S12II - $99
(this thing is rock solid. Seasonic is one of the most reliable PSU manufacturers out there.)
TOTAL: $1,085
I know its a couble bucks over budget but it'd be well worth it.
TOTAL: (without SSD) $1,006
This is just a quick list I threw together and I'm sure it could use some refinement, which no doubt some other TS members will provide. good luck, and if you have any further questions, feel free to ask!
