Samsung EcoGreen F2 1TB Internal Hard Drive & Rosewill RX-DU100 Hard Drive Docking Station for $79.99 shipped.  Here is a screenshot for your reference.  Scroll down the page and select View All Combos to find it as shown as this screenshot.  This 5400rpm drive is designed to be energy-efficient instead of maximum speed, which makes it a more appropriate storage drive than a boot drive.  The docking station accepts either a 2.5" or 3.5" SATA drive.  Most places have this hard drive alone for about $80.
