wait wait wait, you have a sata 3.0 board? Where did i miss that? Are those cables required for full 6gb use of a sata 3.0 board? Or can you still use the old sata cords and get 6gb/s?

Also quick suggestion for you; I don't know if you have ever sleeved much before, but from the looks of it you are/planning using a lighter to shrink the heatshrink(?) If so please don't! For one it discolors the heatshink. It looks "dirty" is the only way i can discribe it. Get a hobby heat blower. Its the best thing for around $15. Past that your into getting a heat gun that costs $50. Just some words of advice.
