Hey mate, glad to see you made it here
Since you live in Australia like me (yay), take a look at some of these stores:
www.pccasegear.com
www.MSY.com.au
www.umart.com.au
www.scorptech.com.au
In my opinion, PCCG and MSY are the best, simply because I've bought from both of them and had no trouble whatsoever.
I have also bought from Umart, but for some reason I didn't really like the place. The website, store, and staff all just struck me as a bit slack. Don't let that deter you though, pick whichever suits your needs the best!
Alright, let's get cracking on your actual rig.
One thing you should probably do first Is decide who is going to be doing the upgrading, because If you're unwilling to perform the surgery on your computer then you need to find someone to do it for you ASAP
Moving on, here's a quick setup I threw together on PCCG.
A few things that are up to you:
1. Colour scheme. Black/blue? Black/red? Black/white?
2. Aesthetics. Silent &sleek, sexy, clean build, or a more Gaming, Windows & LEDS, In-your-face build?
3. Storage? How much do you need? I have a 500GB HDD and I find myself getting along just fine. SSD? did you want one? It's probably a good idea to do so, but it's up to you.
4. Blu ray. you mentioned you watch movies, so would a Blu Ray burner be in order?
5. Fanboyism. AMD or intel? Nvidia or ATI?
6. Do you already have a copy of windows, or do we need to buy a fresh one?
7. Will you be overclocking?
That being said, here we go:
Case: Coolermaster CM 690II Advanced -
$119
Great looking case. Probably leaning toward the more 'flashy, gaming' aesthetics, considering the cool design, blue LED fan, and side window. Excellent features, and great cable management. A friend of mine owns this case, and it's pretty darn good.
CPU: intel i5 3570K -
$233
This is arguably the most popular CPU at this current point in time. With good reason, too.
Quad core, 3.4GHz, Ivy Bridge. K series, so you can overclock if you choose. More than enough grunt to power through any modern day games comfortably.
CPU Cooler: Coolermaster Hyper 212 EVO -
$35
Widely regarded as one of (if not) the best air CPU coolers. This thing should have no trouble keeping temperatures in check.
GPU: Gigabyte HD7870 2GB OC -
$255
This card is pretty darn powerful, you should have no difficulty playing any games at a single screen resolution (1920x1080).
Plus, with Gigabyte's crazy cooling (3 fans!) you should have no difficulty keeping things cool.
SSD: Samsung 830 Series 128GB -
$99
Basically the use for this is to use it as a boot drive, and a select few other programs that you feel need snappy speed. The result? much faster load times when doing general computing. Also, you get to brag about how it takes you less than 10 seconds to boot up. A worthwhile investment.
HDD: Seagate Barracuda 1TB -
$79
7200RPM, Hard drive. not much else to say. I have the 500GB model running in my rig right now, and have had to problems thus far. 1TB should be more than enough for all your moves, music, games, etc.
Memory: Corsair Vengeance 8GB (2x4GB) Low Profile -
$49
8GB, which is more than enough, 1600MHz, 1.5V. excellent set of RAM, and for a pretty affordable price too.
went for the Low Profile set to avoid any confrontations with exuberant CPU Cooler fans.
Motherboard: Gigabyte GA-Z77X-D3H -
$145
Great Motherboard, ATX, plenty of features, and rock solid. Not much else to say. This thing should last you quite a while.
Optical Drive: LG DVDRW -
$21
Generic disk drive, nothing special. Feel free to upgrade to bluray though, but it's gonna cost far more.
Power Supply: Seasonic M12II 620W -
$129
Rock solid stability, more than enough power. Modular design, Active PFC, and 80+ bronze. great Power supply, great price.
TOTAL: $1,165
Alright, that's the list, and

Feel free to comment on any changes/preferences you may have, and sorry for the wall of text. just trying to be thorough.
