Best Buy via eBay offers the open-box Dell Inspiron AMD Ryzen 7 1700 3GHz Desktop PC for $772.99 with free shipping. That's $277 off list, $78 under the factory-sealed unit we saw last week, and the best price we could find. It features an AMD Ryzen 7 1700 3GHz 8-core processor, 16GB RAM, 1TB 7200 rpm hard drive, AMD Radeon RX 580 8GB graphics, DVD burner, 802.11ac wireless, Bluetooth 4.1, and Windows 10 Home 64-bit. A 1-year warranty applies, but it's unclear who backs it.
