Newegg offers the refurbished Lenovo ThinkCentre M71E Intel Pentium G630 2.7GHz Desktop PC for $109.99. This $20 mail-in rebate drops it to $89.99. With $1.99 for shipping, that's $110 off list and the lowest total price we've seen since Black Friday week, when we saw it for $7 less. Features include an Intel Pentium G630 Core 2.7GHz Sandy Bridge dual-core processor, 4GB RAM, 250GB hard drive, DVD burner, Gigabit Ethernet, and Windows 7 Professional 64-bit. Deal ends May 31.

A 1-year warranty applies, although it's unclear who backs it.
