I recently took advantage of the (now expired) excellent Ryzen 5 3600 Ozbargain deal and was looking for a motherboard to go with it (new system build). After reading a tonne of reviews I wanted the B450 Tomahawk but that seems to be hard to get. After googling I found plenty of sites recommending the MSI X470 Gaming Plus Max as a good alternative (including this previous deal at OzBargain).
Looked at PC Part Picker and saw a link to Amazon for $177.75 instead of $189 at CentreCom or the like. Seemed like a good deal.
Never heard of the seller (they're coming up here as PCByte?) but they have a pretty solid eBay presence and its Amazon so I'm cool with it.
