That's the same board I have now. It's still in the box because I can't do anything with it yet. Still waiting for my other parts to be delivered next week. The only thing I've done with the motherboard is to setup the power switch so I can see the fans spin and the LED light up. It looks really cool. Then turned it back off and put the motherboard back in the case.
SATA is suppose to be better than the ancient IDE drive technology transferring data at 150MB/s and higher compared to the ATA133 (133MB/s or less). In sense, it's suppose to be quicker that way, but not a huge significant amount. For that, I would get the Western Digital Raptor SATA drive because it spins at 10,000RPM instead of 7,200 RPM for most drives. Plus, the data cable for the SATA is far thinner than the humongous IDE ribbon cable. It will allow for better air flow within the case. Looks a whole lot better than the ugly IDE "wide load" data cable.
