While there is room for both physical security and logical security when protecting your data, this isn't how it's accomplished. If anything, this is going to make it harder to stop a remote attack because you'll no longer be able to see what's going on or effectively issue commands to thwart the attack. It won't do much against a physical attack either because they can just take the hard drive.
