Right I'm running 5x hard drives in my Mac Pro - 4x SATA drives in the sleds and an old IDE in the second optical bay for Time Machine. I want to add an SSD and would prefer to not pull any drive out - but it's not the end of the world if I pull the IDE drive and use something else for Time Machine backup. I hear there are 2x sata ports on the logic board - not sure where they are, how long can I fish a SATA cable up, and where do I get power from. I don't mind a cheesy solution - I'm the only one who sees the inside of my case anyway. I searched for forums and most of this conversation seems to be about newer Mac Pros that has a Sata port in the optical - links or advice appreciated!
