First Build, Help!

Looking to build my first pc. I've put together this list: https://au.pcpartpicker.com/list/wcPxb2

Hoping to create the best price to performance for around 2k AUD. I have two questions, first is: with the Lian Li 207 case. Is it worth adding additional fans to improve cooling/airflow? If so how many and what kind of orientation?

2nd question: the Gigabyte Eagle Mobo supports the ryzen 5 9000 series but may require an update? Is it possible to know prior to purchasing if it comes up to date? If not, is it easy to do myself?

Please critique the build as much as possible as I won't a good rig for the price but still allow upgrades in the future.

Cheers!
