I don't know if this is a good deal or not, but Fry's Electronics has this
WD 3TB My Cloud Personal Network Attached Storage -NAS : WDBCTL0030HWT-NESN US $139.99 - US $10 (promo code 7221037) = US $129 + Free S/H. If you had Fry's Electronics store near by, you may place an order online and grab it locally the same day. The
specifications indicate this NAS has a built-in USB3 port. I reckon the USB3 port will allow some external HDD addons to increase the NAS capacity? Anyway, its RJ45 port supports 10/100/1000 Mbps.
