Newegg offers the refurbished Acer Aspire AXC-704G-UW61 Intel Celeron 1.6GHz Desktop PC, model no. DT.B0ZAA.001.HU, for $99.99 with free shipping. That's $19 below our November mention of a refurb and the lowest total price we've seen. (It's the best deal for a refurb now by $16 and $149 less than buying new.) It features an Intel Celeron N3050 1.6GHz Braswell dual-core processor, 4GB RAM, 500GB 7200 rpm hard drive, Gigabit Ethernet, DVD burner, USB 3.0, HDMI, SD card slot, and Windows 10 Home. Deal ends January 28.

Note: A 90-day warranty is included, but it's unclear who backs it.
