Newegg offers the refurbished HP Compaq DC7700 Intel Core 2 Duo 2.2GHz Desktop PC (no monitor) for $74.99. This $20 mail-in rebate drops it to $54.99. With free shipping, that's $145 off list, $5 under our refurb mention from two weeks ago, and the lowest total price we've seen for a HP Compaq PC with a Core 2 Duo processor. It includes an Intel Core 2 Duo E4500 2.2GHz dual-core processor, 2GB RAM, 80GB hard drive, DVD burner, and Windows 7 Home Premium 32-bit. Deal ends July 9.

A 90-day warranty applies, although it's unclear who backs it.
