Instead of the ICY Box I showed you in my first post, I was thinking of gong with this Kingwin KF-91 Aluminum case. It has a handle so I can just take the whole harddrive inside of a mount, this way nothing is exposed or messed up during transport. It's $24+ shipping on Tiger Direct.
I want that fabbed and mounted into the center console, along with foam padding for vibration resistance. I will slap in a 1TB SATA HDD in there.
