I was attempting to make a "USB HDD" by shoving a USB Hub and Flash drive together inside a gutted out HDD. But the hub didn't fit... so I was left with an empty shell.
This HDD swings open on a single screw, and can house tons of objects. If you have parts lying around you house, nobody would suspect a thing. You can even close it up, and insert it into a PC drive bay, the PC won't detect it, it will just slide and lock into place, close up your PC case and BAM, you have extra security.
