Beware that the second SATA port may not work
2 - 4 horas
Wanted to add an SSD into the mix
It went well except it seems that the second SATA port on my mini doesn't work. I tried both drives plugged into the first SATA port (the one it was originally using) and all was well. Whenever a drive was plugged into the second one, it wouldn't correctly recognize it. I tried both connectors too, the original one and the one that came in the upgrade kit, so it was definitely the port. Guess Apple doesn't necessarily guarantee that second port is going to work on the non-server version of the mini :(
Be careful not to strip the torque screws and be extra careful disconnecting the fan header. I found the wires came out of the fan header very easily.
