Seems a bit expensive considering you can pick up 95% of that stuff today for a lot less. The only thing you have going for you is the fact that 5830's have not been available for awhile. I might be wrong but the cost brand new for what you listed (excluding the 5830's) is ~$559. That means your charging around 185 per 5830 which is horrible. You'd be better off buying the 6870 (the exact same card that requires less power) for $150 right now and they are available.
