Newegg offers the refurbished Acer Aspire AXC-603G-UW30 Celeron 2GHz Desktop PC, model no. DT.SUVAA.003, for $159.99. A $30 mail-in rebate cuts the price to $129.99. With free shipping, that's $10 under our mention from a week ago and the lowest total price we've seen. (It's a current low by $52 for a refurb.) Features include an Intel Bay Trail Celeron J1900 2GHz quad-core processor, 4GB RAM, 500GB 7200 rpm hard drive, DVD burner, Gigabit Ethernet, HDMI, and Windows 8.1 64-bit. Rebate expires April 30.

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