Yeah the System RAM is WAY overkill. But yeah, that's top-notch hardware you've picked.
Now assuming you're buying from CyberpowerPC or Ibuypower (it looks like their selection screens?) here are my suggestions.
1) No reason for 32GB of RAM on any gaming rig. No games currently utilize 8GB (not even BF3 and FC3), so with 16GB you've got memory to spare for multi-tasking and keeping his machine future-proof for the next 3 years.
Even 16GB of RAM is overkill unless you're running really memory-intensive applications like HD video editing software or professional rendering/design programs like Maya or Blender, or doing heavy-duty work in Photoshop or AutoCad with multiple big files open. Those types of workstations really need 16-32GB of RAM, not gaming rigs.
2) If you want the ability to use 32GB of RAM for the types of non-gaming tasks described above, you'll need Windows 7 Professional. Home Premium maxes out at 16GB.
3) A pair of 120GB SSDs in RAID isn't really cost-effective (and RAID 5 requires 3 drives- I think they'll flag that later because their automated configuration screens allowed it)
SSDs greatly speed up Windows startup and the initial launch time of programs, but that's all. They don't improve performance once you're past the splash screen and into the game. So it's great to have a SSD for the system drive and the HDD for installing programs and storing data, but the benefits of RAID for SSDs are negligible compared to the cost. And the write cycle limit of SSDs means you'll probably have to replace it after 2-3 years anyway.
4) A pair of GTX 680's in SLI is Galactus level overkill for Skyrim (though appropriate for Crysis 3). Even a single GTX 680 is effortlessly capable of maxing out Skyrim. Which brings me to the whole SLI vs single-card discussion. In general, a single higher-end card is preferable to an SLI or Crossfire combo of lesser cards. SLI/CF sometimes provide a great performance boost, sometimes not. There are tradeoffs to multi-card configurations.
First off, dual cards greatly increase heat, noise and power consumption. Your 1000W Certified PSU can handle the latter, but even that isn't the ideal choice. With really high-end components like these, don't take anything less than a top-notch branded PSU from Corsair, XFX, Seasonic, Antec, Lepa etc. A higher total wattage rating is no substitute for PSU quality. An 850W Corsair beats a 1000W generic unit.

Now back to SLI. Performance doesn't scale equally in all games. In some games you'll see 100 percent improvement over a single card but in others the gain is only 60-80 percent, in others only 30-40 percent and in some SLI isn't supported at all, so dual cards don't perform any better than one. In particular, Skyrim isn't a dual-card friendly title. Gains are modest compared to titles like Battlefield 3 and STALKER.

Next, SLI does *NOT* double your VRAM. Because each card maintains a copy of the same data, SLI and Crossfire pairs only have the effective VRAM of a single card. So a pair of 4GB cards function as a faster 4GB card, not an 8GB card.
Also, dual-card configurations run afoul of weird sporadic driver issues/bugs more frequently. Things like monitors not waking up properly after the screen is blanked or the system goes to standby, textures or colors occasioanlly not displaying properly, the occasional freeze/crash etc. Finally, any dual-card configurations might experience micro-stuttering:

I suggest at least considering a single GTX 690 (which is a dual-GPU card) as an alternative. If money is no object, a pair of GTX Titans is the most beastly SLI option under the sun, although still potentially subject to the glitches mentioned above.

So.. food for thought! I'm thinking with 16GB of RAM and a single SSD you might free up enough $$$ to give yourself some flexibility in the GPU arena.
