Going to build my first ever PC - Suggestions and input welcome

[starcraft]

Hi all

I PC game on and off, but I have never built my own PC.  In Australia, all parts are more expensive, but purchasing a pre-built system is particularly prohibitive.

I am looking to spend approximately $8-900 Australian on the parts.  This link represents a pretty well known and cheap Aussie supplier, but I am perfectly open to suggestions.

I am certainly checking out Youtube videos on things you need to know about building your own PC, but I would certainly welcome input on:

 

• The best parts to fit together in that budget;
• General suggestions around building your own PC, the sorts of things someone new might not be aware of (construction space, compatibility issues, extra cords I might need, ideal space and power supple - I know NOTHING about motherboards etc); and
• Any suggestions for where else in Australian I might purchase parts.

My current monitor is 1080p - I don't envision going much higher than that, but if the budget would allow enough power to run a theoretically higher resolution monitor, who knows, I might get one one day!

All input welcome and greatly appreciated.  My goal is to build a computer to use and enjoy, but half of the experience is doing it myself and proving that I can!
