Yes, buy an enclosure yourself and an internal seagate 3.5" hard drive with 5 year warranty. IDE enclosure will be cheaper than a Sata enclosure, but you can do either one. Buy a good enclosure .. it's worth it. Price will be around the same or cheaper, depending on how much you end up paying for shipping to Hawaii, and you get a better/faster drive with a better warranty for the money. They are simple to put together.

Note that's a 160G 7200RPM IDE drive. Drive + enclosure for around $100 plus shipping. The 160's are only a few more dollars than the 120s.
