Is the power supply enough?
Yes, that's a good power supply.
That's a very good system indeed. You won't regret using the two Raptor drives, I have two x the 74Gb Raptors in a RAID 0 and I can say most emphatically it does speed things up. Are you going to use a RAID 0 setup? It will improve things if you do.
They are a tad noisier than other hard disks though.
Don't even consider Nortons, a complete waste of money and will kill off all the speed advantages you've gained with the Raptor drives.
If you want to pay for Anti Virus software get Kaspersky or NOD 32. Or use AntiVir or Avast for free.
Your 4Gb of memory will likely show only 3Gb or 3.5Gb under a 32 bit operating system, you sure you don't want to stick with just 2Gb? There are ways around getting the 4Gb to show but it doesn't always work. This is something I found out the hard way.
The case is expensive, I certainly wouldn't spend that much on a case but if you like it and you have the cash then go for it.
And as mentioned above, get yourself a DVD-ROM drive to complement your burner, so much easier when copying a disk and they're only about £14.00.
Good luck with the build, all that kit - with the exception of Nortons - looks superb
