I know OCZ's PSUs are good...not sure about Corsair, but the reviews on them are pretty good. They have plenty of amps too. The 15,000 rpm hard drives are not worth it at all. If you really want a fast hard drive for the OS, just get a 10,000rpm hard drive, like the WD Raptors.
I was looking at your list, and I noticed you went for the e6700. Don't get that either....not worth the extra $200 for a 200mhz increase over the e6600. Just get the e6600 and overclock past it.
