Hello, I'm not Setsul but I pretend to know a bit about computers every now and then.
- Do you really need an i7?
- Why do you have a K CPU but no cooler? If you don't want to overclock, go for a non-K CPU, otherwise I'd suggest a Noctua NH-D14.
- Why a single stick of ram?
- Tbh I was never a fan of SLI when there are better single card solutions out there. Plus it would also allow you to get a cheaper Motherboard and PSU.

I included a 250GB SSD, since the 128GB variant is only 20$ cheaper. You should be able to get this PSU for 100$(I hope), if not try to go with a GS 550.
P.S.: I have no idea about aussie prices so if there's a cheaper alternative for a certain part feel free to call me out on it.
