Need help with building a PC please (especially case)

Hi, i'm building a PC for the first time as I want to start streaming games. No need for peripherals. Just need to make sure my tower is pretty good. I don't have parts yet for the case and psu. I am also not sure if i'm supposed to buy fans for the case or if the case comes with it, but i'd like as much as possible to keep the computer cool.

Link for MSY: http://www.msy.com.au/stores

Approximate Purchase Date: Asap I guess, i'm just really excited

Budget Range: $1800 AUD

System Usage from Most to Least Important: Gaming, Streaming, Surfing the net, Photoshop?

Are you buying a monitor: No

Do you need to buy OS: No

Preferred Website(s) for Parts: Limited to MSY pls. I plan on getting all parts there (Probably not the case as MSY doesn't really have that many good cases.)

Location: Auburn. MSY has an Auburn branch that i'll be buying parts from

Parts Preferences: Quality > Brand

Overclocking: Maybe

SLI or Crossfire: Maybe (Don't know what that means)

Additional Comments: Need help with building my first PC. When searching MSY, can you please check if there is stock available in their Auburn branch?
Also, if you don't mind, could you please check if all my part are compatible with each other?

And Most Importantly, Why Are You Upgrading: Planning on streaming. Not really upgrading, just buying PC parts and making one.

Include a list of any parts you have already selected with descriptively labeled links for parts. Please do not post only links.

I need help with the case and psu. I don't know what to go with. All I know is that I want at least 650W PSU and a case with LED lights that can fit my motherboard and that has quite a bit of fans to keep my PC cool.

Preferably using MSY Auburn but if theres nothing that fits that criteria, then PC Case Gear would be fine too.

Edit: Would the Corsair CCSPEC-03 Carbide SPEC-03 Black USB3.0 Mid Tower Case without PSU
be good? $85
