I am building a new system. I want this one to be pretty high end and was wondering if I would benefit greatly from adding a second HDD and setting it up as Raid? Also can I initially build the system without Raid and add/configure a second HDD later?
Here are the components. The plan is to buy another IDential HDD. This is a gaming Desktop.

There is generally no real world(vs. synthetic transfer rate benchmarks) performance advantage to raid of any kind using motherboard raid. I saw no benefit when I tried it some years ago; not worth it to me.
There are some specific applications that will benefit, but
gaming is not one of them. Even if you have an application which reads one input file sequentially, and writes
it out, you will perform about as well by putting the input on one drive, and the output on the other.
For best performance get a SSD for the OS and a separate large storage drive.
6 core cpu's or even 4 core cpu's do not improve performance unless your application or game are multi core enabled. It is better to get a fast dual core cpu if that is the case.
I like the tower type heat sinks with a large, slow turning 120mm fan. Most any will do. You should be able to find one for <$40.
For gaming, the graphics card is usually much more important than the cpu.
RAID 0 would increase performance by 1.5X roughly (mine did).
I've seen benchmarks on that Samsung drive, and they were close to my 2xSeagate 7200.11 500GB RAID 0 array.
But, still a far cry from a SSD, and no HDD comes close to the SATA II bandwidth, as SSD do. My HDD array peaks at 150MBps, half of a single SATA II specs.
And yes, you'll have to reinstall Windows if you add a RAID 0 array later.
Some would say it's worth it, some will swear never do it, claiming drive failure. Just back up frequently. But most will say get an SSD for OS and PRograms, and a large fast HDD for data/media, like the Samsung Spinpoint. I say get a single SSD. Intel X25-M 80GB.
True, synthetic benchmarks of raid-0 are impressive, but they do best measuring sequential transfer rates of large files. Something I rarely did in the real world. With conventional hard drives, I hardly noticed any difference. I did try raid-0 of two small SSD's to get a larger system image, and that worked out well.
