B&H Photo-Video offers the QNAP Diskless System 2-Bay All-in-One Network Attached Storage Server, model no. TS-220, for $139.99 with free shipping. That's the lowest total price we could find by $76, although we saw it for a buck less in October via in-store pickup. It features a Marvell 1.6GHz processor, 512MB RAM, support for two SATA drives, two USB 3.0 ports, one USB 2.0 port, and one Gigabit Ethernet port.
