As one of its daily deals, Caloby offers the factory-refurbished Dell Inspiron 660 Intel Ivy Bridge Core i5 2.7GHz Desktop PC (no monitor) for $449.99 with free shipping. Although we saw a new unit with a dedicated 1GB GPU at this price last September, it's still $250 off list and the lowest total price we could find today. Features include an Intel Core i5-3330 2.7GHz Ivy Bridge quad-core processor, 8GB RAM, 2TB 7200 rpm hard drive, DVD burner, 802.11n wireless, media card reader, and Windows 8 64-bit.
