Doug, I suggest renting server space at someplace like serverbeach.com. Three hard drives in the same box is overkill. Any event that takes out two drives will take out all three. Better to use one or two drives and replicate the data to a geographically remote server if you're that worried about backup. But really, if it's just forum posts, it's not a catastrophe to lose a few, so just running a nightly script to back up new posts to your home PC should be enough.
