Yeah, if you want to run that HDD you'll have to get a PCIe SAS card. I would pick out a different hard drive, since that one is an enterprise drive. WD Blacks are a pretty good choice, as are Seagate Barracudas.
Nice catch, I failed to notice that SAS. Replaced it with another Seagate. Already you guys have saved me a headache thanks. Here's a pic of the updated build, let me know if I missed anything else. Thanks folks.
Thermaltake TR2 RX 750 W is, according to our methodology, a flawed product that must be avoided at all costs. It can’t deliver its labeled wattage at high temperatures, but this is not the worst of it: ripple and noise level are way above the maximum allowed when you pull 80% or more from the unit’s labeled capacity (i.e., 600 W and above), overloading your components (especially electrolytic capacitors from the motherboard and video cards), which can cause your PC to present an erratic behavior (crashes and random resets) and, under extreme conditions, damage components.
