Not a bad first spec, however, there are a few things I would suggest changing.
The CPU is great, but you should still be able to get an i7 920 chip for a good deal less than a 930 if you know where to look.
The motherboard is also excellent, great choice.
However, the GPU is a bit on the old side. For the same kind of money you can get the faster DX11 ATI
HD 5850, or are you needing the Nvidia-only features?
The PSU is fine, personally I would suggest spending a bit more on something by Antec, Corsair or Seasonic, but the OCZ is a decent PSU.
I have only heard good things about the Zalman case, so it looks like a good case for the money.
The RAM however is not quite right. This RAM will work fine and run in dual channel mode - however the X58 is able to run 3 sticks of RAM in triple channel mode for even more memory bandwidth. Also the 3 stick kits cost less per GB than the 2 stick kits in general. Therefore it would make a lot of sense to get a good 3 stick kit (3x2GB) like
this one.
The Toshiba drive you picked looks a bit crappy in comparison to all the top-end kit you are putting it with. I would suggest a drive like
this if you are not planning to get an SSD.
DVD drive is fine.
CPU cooler is one of the cheaper ones, but it is a good unit. It is relatively quiet and will allow you to give a decent overclock to your i7 chip. However, if you are aiming to overclock to 4GHz or more then you should consider something beefier like a Prolimatech megahalems.
Best of luck with your first build. Have you got a good monitor, keyboard, mouse and headphones/speakers to use with your new system?
