Same eBay seller that has the i5 8400 / GTX 1060 bundle from a couple of days ago - I went through their listings (there are a buttload of variations on a theme) and found this newby:
Case: TechFast Leaper Case
Case Fans: (1x) 120mm Front Red LED Fan
Power Supply: 550W Power Supply
Motherboard: A320 Motherboard
System Cooling: Stock Cooler
Processor: AMD Ryzen 3 2200G Quad Core Processor (3.5GHz Base Clock - 3.7GHz Max Clock)
Graphics: Single AMD Radeon RX 570 4GB Dedicated Graphics Card
Memory: 8GB DDR4 RAM (1 x 8GB)
Operating System: Windows 10 Home Edition
Primary Drive: 120GB Solid State Drive
Storage: Not Included; see PC Upgrades section below

$599 for that with a 20% POINTY code discount on top brings it to $539 delivered…
They're also selling the individual cards from both deals:
Strix RX570 4GB: http://www.ebay.com.au/itm/192649714906
Asus GTX 1060 6GB: http://www.ebay.com.au/itm/192661697804
Mod Note: OP is associated with Techfast but did not declare it.
Only if that's a B350 motherboard…
