Newegg offers the iStarUSA Serial ATA 6Gb/s Hot-Swap Drive Cage, model no. BPN-2535DE-SA, bundled with the Mediasonic PCI Express USB 3.0 ProBox Card, model no. HP1-SU3, for $23.99. (The card will automatically be added to your cart.) Redeem this $10 mail-in rebate to cut it to $13.99. With free shipping, that's $32 under the lowest total price we could find for these items sold separately elsewhere. (For further comparison, we last saw the drive cage for $4 less in March.) The hot-swap capable chassis enclosure fits a 3.5" drive bay, holds two 2.5" hard drives, and supports SATA III. The PCI express card features two USB 3.0 ports and transfer rates up to 5Gb/s. Rebate expires July 31.
