I just purchased a 6th gen iPod classic. It is the 160gb thick version with a bad hard drive and I'm looking to replace it with one of Tarkan's iFlash SD adapters (I'm aware of the 128gb limit this generation has when upgrading the drives). Could I fit a thin back housing to replace the thick housing so that the adapter doesn't rattle around as much? If so, what would be required to allow the internal parts to fit?
