Brave going with a hackintosh for this. I found the install + update + rebuild issues were too painful to consider using in times of dire need. I would go with a thunderbolt based drive enclosure with a mac-mini. EG A Lacie 5big.
PS. This is a thread I'd like to read but probably won't remember to as the updates to it won't show up as the most recent posts.
Do consider putting your updates in as normal posts rather than edits to the old posts. That's how 99% of logs are run here on BT.
