Walmart offers the iBuyPower AMD FX-Series 3.8GHz Desktop PC (no monitor) in Black/Blue or Black/Green, model no. WA550G, for $409 with free shipping. That's tied with last week's mention as the lowest total price we've seen. (It's also $56 under the best deal we could find for a similar system elsewhere.) It features an AMD FX-4300 3.8GHz quad-core processor, 8GB RAM, 1TB hard drive, Nvidia GeForce GT 730 2GB graphics, DVD burner, Gigabit Ethernet, HDMI, USB 3.0, and Windows 10 Home.
