Horrible build all around. You've got an OEM CPU, but no heatsink. That means it's going to burn up when you try to boot. Second, you've got an overly pricey board, slow RAM, a poor quality PSU and a poor quality case. You're wasting money on a VelociRaptor when the other drive (and others) are just as fast but a lot cheaper.
"Horrible build all around. Here's a much better one:" is MadAdmiral's shorthand for "your proposed rig would work better if you made these changes."
Upon reviewing your proposed build, I'm in agreement with MadAdmiral.
CPU/GPU - faster/more powerful choices
HDD - the Velociraptor offers very poor value these days. Costs a lot more than a traditional hard drive, and with the availability of relatively inexpensive SSDs, you are a lot better off going with an SSD + a good 7200 rpm drive, or simply going with the 7200 rpm drive. Also, while the WD1002FAEX is marketed as a SATA 6 Gb/s drive, there is no way that it reaches SATA 3 Gb/s speeds, much less 6. The only drives out there that can saturate SATA 3 Gb/s are a few SSDs, and the newest Velociraptors in very very short bursts.
PSU - MadAdmiral's suggested PSU is more efficient than the one you picked, and less likely to fail.
RAM - MadAdmiral found a set with better timings for just a few dollars more.
That CPU does not support DDR3. You will need to get an AM3 CPU, like a 945, 955, 965, 1055T, or 1090T to use that motherboard and memory. That PSU is little overkill, that RAM is a tad pricey, and I have no experience with that particular case. I would also buy a SSD before I would buy a Raptor.
