Icy Dock has a new SSD to desktop hard drive conversion kit that is very easy to work with. It has a tool-less design and accepts SSD and notebook hard drives of varying heights. It essentially converts those drives into a form factor that will fit into a NAS or other drive enclosures that only accept a desktop drive.
This is a revision on their prior EZConvert design. This new one has better airflow and is much easier to work with. I recommend it!
