I bought a load of these a while ago...
The most useful tool on the planet. I have several of these in systems, if a friend or family member system dies - I can take their drive, and put it in any of my rigs and means I can get to the data - or fix the boot problems.
No rails - no open chassis, clean, quick and easy
