Hi all,

I'm planning on building a new PC soon, current one is getting a wee bit crusty.
I'm looking for some input into specs and prices, as I only have a vague idea of what I'm talking about.

I've grabbed prices off of two sites, MSY and AllNeeds. (msy.com.au/default.jsp, allneeds.com.au)

Part	MSY	AllNeeds
CPU: Intel i5-2500K	$221	$225
Mobo: Gigabyte GA-Z68XP-UD4	$219	$212
Case: No idea, o_O	<$200	<$200
PSU: Same thing, >800W	<$170	<$170
RAM: Kingston KVR 8GB (2x4G)	$55	$58
Graphics: 2x nVidia 560 (Asus)	$432	$480
or: 2x nVidia 560 Ti (Asus)	---	$538
Optical: DVD	$24	$24
Blu-ray Writer	$85	$88
HDD: SSD - 128 GB	$198	$222
Traditional - 1 TB	$58	$58
Windows 7 64-bit HP	$95	$89
----------------------------------------------	-----------	-----------
	$1757	$1826
	or	$1884

Okay, and a bunch of specific questions.

What is a good Case/PSU combo? I don't require anything fancy, it just needs to hold the stuff and power it.
Is it worth going for 2 560's or should I go for a single 570?
Is there enough of a difference between a 560 and 560 Ti to justify the price difference?
Is there anything here that can be replaced with something cheaper that is close enough to the same performance?

This is gonna be a bit more expensive than I hoped but with something like this I could smash out some streams.

As a final note, I noticed the other PC build thread. I decided not to hi-jack his since were working in difference currencies and have different enough aims, as far as I'm aware. If I should chuck this in his, just let me know.

Looking forward to everyone's input.
