I'll preface my post by saying that I am not a tech, expert, or even know what I'm talking about. I am a person who's on the verge of purchasing/building a video editing PC within the next month. I have been doing research this whole summer and the following is what was suggested to me here on tomshardware.com. This is my first response to any post I have ever read. For a while I couldn't get anyone to help me out with a Non Gaming Build so this why I'm posting this response.
---
System Usage from Most to Least Important: Multimedia - Video Editing (Adobe Premiere Pro CS5), Music Production (Avid Pro Tools 9), Graphic Design (Adobe Photoshop CS5). I am interested in gaming but I am willing to completely rule it out if it conflicts with my video/audio tasks. Games I'm interested in - Battlefield 3, ARMA 2, America's Army 3, and other First Person Shooters. Finally, general PC use (Microsoft Office, Web Surfing).

Your Build
Case: Cooler Master Storm Scout $ 80
http://www.newegg.com/Product/Product.aspx?Item=N82E16811119196
PSU: Corsair AX850 850W $190
http://www.newegg.com/Product/Product.aspx?Item=N82E16817139015
I found this to be the best PSU for my needs. It is completely modular and it is enough power if you want to get another GTX 580 for SLI at a later date. I don't plan on ever getting a second GPU for SLI but I'm covering that base. The AX850 is only $20 more than the AX750. A 1000W PSU is recommended if you plan to overclock which is not the case for you. So this is a future proofing choice but it is also an area where money can be saved.
Mother Board: ASRock Z68 Extreme4 Gen 3 $190
http://www.newegg.com/Product/Product.aspx?Item=N82E16813157264
Max 32GB RAM 4x8GB Sticks.
The Z68 Motherboards have many useful features.

The only selection that everyone agreed on being the best choice throughout my research. Bang for the money. I don't know how it compares to your CPU selection.
RAM: Ripjaws X 8GB 1600 (2 x 4GB) (x2) $120
http://www.newegg.com/Product/Product.aspx?Item=N82E16820231428
These RAM sticks fit under my CPU Cooler. I wanted Corsair Vengeance Sticks. Make sure you get the right RAM that will fit under your cooler. I think you should go with 16 GB and at a later date upgrade to 32GB.
CPU Fan: Noctua NH-C12P SE14 $75
http://www.newegg.com/Product/Product.aspx?Item=N82E16835608019&nm_mc=AFC-C8Junction&cm_mmc=AFC-C8Junction-_-RSSDailyDeals-_-na-_-na&AID=10521304&PID=4176827&SID=3fqwc51qgwsi
Stock CPU Fans are always good enough to cool your CPU but it was recommended to look into after market cooling. My initial choice was a Noctua NH-D14 but I ended up selecting the Noctua NH-C12P SE14. The Noctua NH-D14 is the ultimate cooling solution for overclocking your CPU. It is considered to be the best "Fan" CPU Cooler. Since that is not the case for you (Like me) I chose to go with the Noctua NH-C12P SE14. It cools your CPU and draws air over your other parts on the motherboard. It is an excellent cooler. It will keep your CPU & Mother Board cool and be very quiet while doing so.

The Cooler Master Hyper 212+ $30
http://www.newegg.com/Product/Product.aspx?Item=N82E16835103065
GPU: EVGA GTX 580 Superclocked $480
http://www.newegg.com/Product/Product.aspx?Item=N82E16814130590
I, Like you, want to do some light gaming. I initially chose that very same 3GB EVGA GTX 580 but I was told I did not need such a powerful card. Those 3GB that you are being charged for are mostly for multi display super high resolution setups. I chose this single Superclocked GTX 580 over any other SLI setup for future proofing. There are less expensive, even faster SLI setups available but it wasn't something I was interested in. It is better to get the higher end card of today for a PC that is going to be used for a long time than yesterday's cards that are great today but not quite so good in the future. That drove my decision.
HDD: Samsung Spinpoint F3 (x2) $120
http://www.newegg.com/Product/Product.aspx?Item=N82E16822152185
These are the most recommended/reliable drives I have found and read about anywhere on the internet. You should get 2 to backup up your data. I don't really like RAID configurations and oversee all of my backups manually. I also have my data stored on a third external drive.
SSD: Crucial M4 128GB SSD $220
http://www.newegg.com/Product/Product.aspx?Item=N82E16820148442
There are newer faster SSD's out now, but these are tried and true. Not many problems being reported by current owners.

You didn't list an optical drive. These are my two choices. I think in a video editing build a Blu Ray Burner is a good choice. I am getting 2 optical drives for disc duplication tasks. You can find other Blu Ray Burners for just under $100.
Here's a link to Blu Ray Burners (List):

OS: Microsoft Windows 7 Professional $140

Total: $2,038.86
Total (Swap the Cooler Master Hyper 212+ for the Noctua NH-C12P SE14 Cooler): $2,084.86
All of these totals are from newegg.com but I recommend buying from amazon.com. I will be saving over $200 on my complete order from amazon. Once you add the totals for taxes and shipping & handling from newegg.com the better deal is over on amazon.com.
To me these are the best available parts/selections for a multimedia build with decent gaming without going over budget.
I hope this is helpful to you. Good luck finding all of the right parts for what you need (I know it's for your friend).
