I think the hard case won't fit it, only leather and silicone iPod cases that can adjust to the size. The 2nd gen's back part is a bit curved the 1st gen is flat. You can consider looking into iFanatic’s ipod cases, I just purchased one… the material they use is called cashmere silicone. It is perfect for me - does not make the iPod any bulkier and the screen is still as clear.
