Help me build my gaming pc

Hey guys, my name is Jackson, I’m 26 years old in from Brazil but at the moment I’m leaving in New Zealand.

My whole life I have been following big streemers and I always had the dream of being able to do the same thing but as everyone knows for you to be able to do this you need a good computer but in brazil it is very expensive and in New Zealand I trying to stabilise my life (work, visa), I would like your help to be able to make that dream come true. I currently have a PS4 old model but my passion is mouse and keyboard. I managed to raise the money for the PC I will donate my PS4
