OCZ don't make the best power supplies, although they own PC Power & Cooling, the ZT Series isn't the best. Honestly 650W should run it, but if it doesn't have the 6 pins you need, its not recommended to use molex to PCI-e adapters. Might be worth it getting a little more expensive PSU, such as a TX750 or something for like $150.
Don't spend so much on a keyboard, I think a Microsoft Sidewinder X4 will do you well, its only mouses in which you'll get an advantage for getting a costly one, even then, its return diminish really quickly. Maybe you could use money saved on a keyboard to go towards a better power supply
Please do not get a $109 Micro ATX board. That is a giant rip off, and isn't Xfire/SLI compatible as far as images go. Go for an Asrock Z77 Extreme 4 for a couple of bucks more.
I wouldn't go for that 7870, but rather this one.

Its only a tiny bit down on the core, which can be easily regained probably without a voltage change. Its also clocked higher on the memory, and to boot, you get one of the best and oldest Radeon card makers. Its also cheaper
Cold Cathodes are completely crap when it comes to Bitfenix Alchemy's. Jeeze I have a white one and the lighting is so much more effective.

Sure its half the length but 2m of cable probably won't fit in your case either.
Get an overclockable CPU, even if you don't overclock it. Its always handy if you change your mind, especially since you are getting a Z77 based board.

Also get a CPU cooler, much quieter and effective. This one is regarded as the best value for money cooler.

While you are at it, get lower profile ram as well, 1.5 V ram DOES NOT need a heatsink, it just looks ugly with all the height.

Its the same price as well.
I'll make a complete build off my suggestions in a moment, I live in AUS as well, but I don't have an account for PCCG. gotta make one
Edit: Couldn't find Sidewinder, sorry.

Its a tad bit more expensive but a MUCH BETTER build overall. Tell me if I missed something, I most likely did. Should be a bit more expensive than that, might of gotten something wrong. That PSU is also capable for two 7870's as it has the right connectors, and its also higher wattage and of better build.
BTW, you removed the motherboard from your wishlist, so it makes it look like my build is ALOT more than what it should be, its only like $130 more, but you could save more getting a cheaper keyboard and what not.
