Western Digital Caviar Green 1TB 32MB Cache SATA Internal Hard Drive for $71.99 shipped after a $15 rebate. Here is a screenshot before the rebate for your reference. Note that it comes in OEM packaging, which means no pretty retail box but is otherwise identical. This is part of Western Digital’s GreenPower lineup, which reduces the power consumption.
