I just spent 20 minutes doing some searches in all the usual suspects (Amazon, eBay, AliXpress, and some online stores I can usually get good prices from) and the cheapest I found for the configuration you specified was around $400..
Mostly it seems to be the RAM that boosts the cost. For 8GB I can get it down to $260, but I've seen nothing even close to $180.
Edit: I see elsewhere in the thread it's a Beelink from Amazon. Around ~$237 is still the cheapest I can find..
Still a good price.
