Dell Small Business offers the Dell OptiPlex 3020 Intel Haswell 3.3GHz Mini Tower Desktop PC for $629 with free shipping. That's $384 off list, tied with our mention from a week ago, and the lowest total price we could find. (However, we saw it for $20 less a month ago.) It features an Intel Haswell Core i5-4590 3.3GHz quad-core processor, 8GB RAM, 1TB 7200 rpm hard drive, DVD burner and Windows 7 Professional 64-bit (with a license for Windows 8.1 Professional).
