After Deployment Present Build (First Build)

Your budget is pretty high for what you're proposing, but can get some real killer items! Here is something I put together (please take the case even if not the build, it has amazing airflow):

CPU: Intel 3930k
http://www.newegg.com/Product/Product.aspx?Item=N82E168... - $590

CPU Cooler: V10 Hybrid (for some nice overclocking)
http://www.newegg.com/Product/Product.aspx?Item=N82E168... - $116

MOBO: ASUS Rampage IV Extreme
http://www.newegg.com/Product/Product.aspx?Item=N82E168... - $430

Case: HAF X (942)
http://www.newegg.com/Product/Product.aspx?Item=N82E168... - $200

+1 Case Fan on Top: Cooler Master 200mm Red Led Case Fan (will drop temps by about 3 degrees celsius)
http://www.newegg.com/Product/Product.aspx?Item=N82E168... - $24

RAM: Your friends  

SSD: OCZ 240G (Your samsung is good, but this $20 dearer options will outperform. However, it is your choice)
http://www.newegg.com/Product/Product.aspx?Item=N82E168... - $300

HDD: Western Digital Caviar Black 1TB 7200rpm
http://www.newegg.com/Product/Product.aspx?Item=N82E168... - $120

PSU: Cooler Master Silent Pro Gold series, 1200W 80+ GOLD (Amazing, clean power, only the finest for this system. By the way, you wouldn't need 1200W unless you were going quad SLI haha)
http://www.newegg.com/Product/Product.aspx?Item=N82E168... - $240

Optical: LG Lightscribe Blu-ray read/write + 3D support
http://www.newegg.com/Product/Product.aspx?Item=N82E168... - $65

GPU: ASUS GTX 680 (nice choice)
http://www.newegg.com/Product/Product.aspx?Item=N82E168... - $500

Grand Total = $2585

Now, onto the second issue. If you wish to remain at this price, which is right at the beginning of your budget, that is great. If you are willing to spend $500 more, obtain a second GTX 680 and let the world be at your feet (ok, that would be overkill haha)! Otherwise, you should obtain a monitor, which I didn't include (sorry if you don't have one). Here is my suggestion:

Monitor: Samsung Syncmaster 27" 2560x1440
http://www.newegg.com/Product/Product.aspx?Item=N82E168... - $850

Hope that this is what you were looking for! And for an OS, just get a 'free' copy of windows 7, or you can spend $100 if you feel the need!

I've been looking at these and the HAF X seems huge. Any other cases that might be a little bit smaller that come highly recommended?
