The one you linked is the bare version. The desktop version ($20 more) contains a mounting bracket and cables + Norton Ghost. The notebook version (also $20 more) contains what looks like a USB adapter and Norton Ghost.
When I bought the 830 for my desktop, I needed the mounting bracket which cost me $10 to buy separately and didn't work as well as the stock one would have.
Definitely consider opting for the notebook package if you need it.
