Sorry, but this will be anything but "bad ass". You bought an outdated motherboard that only supports slow, outdated RAM and four outdated dual-core CPUs. AMD is nowadays up to 16 cores per CPUs in servers and up to 8 cores in desktop systems.
So a modern high-end desktop will perform better (for the same price or less, I would think) and a modern server will perform times better.
Also, modern SSDs most likely will perform better than those disks for the same price or less.
But anyways, what you need to connect the disks is a PCIe to FibreChannel adapter, something like this: http://www.newegg.com/Product/Produc...hannel&x=0&y=0
When I look at the prices alone for the adapter, you could easily have built a bad ass machine alone with that and a really powerful system with what you have paid at all (I can only speculate about that, but I have seen the average prices for those used parts).
Next time when you built a machine and are "out of the game" I would recommend to get some infos before buying anything.
