New build, need help picking components.

[Mr.Untitled1024]

Budget (including currency): 9100 Rand (South Africa)

Country: South Africa

Games, programs or workloads that it will be used for: gaming mostly.

Other details (existing parts lists, whether any peripherals are needed, what you're upgrading from, when you're going to buy, what resolution and refresh rate you want to play at, etc): I have a bad intel build I want to upgrade from, I have a newish GTX 1650 that I will be using in the new build. also I have a hard drive and a sata ssd that i will be using in the new build. The problem with building pcs in South Africa is that there is no amazon, unless you want to pay a crazy amount of shipping ect. So I want to go with amd, the Ryzen 5 3600 and i'd need a motherboard with that and ram, and I will need a new power supply and if at all possible a new case. I don't know what motherboard to go with that is cheap but to terrible and I want some high frequency ram because I'm going with amd but I don't know how that fits in my budget. Any help with motherboard, ram, PSU, or case will be appreciated. I am avoiding EVETECH becuase I actaually ordered from them and after 3 weeks of nothing they just said they are out of stock and offered me a terrible deal as a replacement, so I asked for a refund. I asked a Computer World shop near me about the Ryzen 3600 and they said they have it in stock, so I will be buying it from there.
