Newegg offers the refurbished Lenovo ThinkCentre M52 Intel Pentium 4 3GHz Desktop PC for $79.99 with free shipping. That's $81 less than the lowest total price we could find for any ThinkCentre M52 elsewhere. This PC features an Intel Pentium 4 3GHz processor, 2GB RAM, 80GB hard drive, DVD-ROM, and Windows 7 Home Premium 32-bit. Deal ends December 2.
Note: A 90-day warranty applies, although it's unclear who supports it.
