There was a storm that went into my area so my internet connection is spotty and can't check the list prices of multiple stores that is locally to you, but:
From www.computersonly.co.za:
AMD Ryzen 5 1600
ASUS Prime B350m-A
HyperX 8GB 2666 DDR4 x 2
MSI GTX 1060 6GB OCV2
Samsung 850 Evo 250GB
Seagate 2TB 7200rpm
Cooler Master V550 Gold Full-modular
Cooler Master Masterbox Lite 3
Listed cost: R17,693 roughly $1305.
Two single DDR4 module due to limited availability of 2 DIMMs kit available for sale at that store. 850Evo because the budget SSD, Kingston UV400 is just ~100 ZAR less; the price increase is worth it for the performance difference. 2TB 7200 rpm Seagate for storage.
CM V550 Gold because the next lowest cost is the mediocre CM B series. Otherwise if you can find any of the Seasonic S12II, M12II, Andyson M5+, Corsair CXM gray label, FSP Hydro in that 500-600W capacity for less than the the CM V550 then feel free to switch to those.
CM Masterbox lite 3 was just selected in attempt to fit into the budget.
If shipping and/or other hidden fees drive cost too high, feel free to drop the SSD or the GTX 1060 to a GTX 1050Ti.
