First Thanks. Your parts and guides have (hopefully (still doing a restore)) shown me how to upgrade my HDD to SSD! I would warn extra caution on the 2 small sets of connectors with the bendy pins. Both the cases on mine were broken. Presumably when it went into Apple for a new Graphics card. I found it very difficult to line the pins up and had to straighten them several times before I could reconnect them. Probably due to the cases being broken and not helping with alignment.
