XFX 550w or 650w
XFX is the only brand I know that had not one but two samples of a PSU blow up in a test. I don't know if their quality control has improved, but it's the brand I would least recommend.
One of these would be good: Seasonic G 550W, Seasonic X-650 or Kingwin 550W.

cooler CPU Noctua NH-U14S Socket Intel/AMD
Solid base, no problems. Noctua cooler is great, but a little expensive. Thermalright Hr-02 Macho or Thermalright True Spirit 140 are just as good, just a little less expensive.
16GB is a lot, if you want to save some money get 8GB. There's no downside to 16GB except price.
Case Tower Cooler Master HAF 932 Advanced ATX
On the upside, the airflow is good with so many large fans. It's huge, the fans aren't quiet and it's really designed for watercooling for which it is probably very good.
Good quiet and dampened cases are Antec P183, Fractal Design R4 and Corsair 550D among others. These are just about as good as you can buy off the shelf.
SSD Samsung 840 UltraSlim Series 128GB Pro 2.5" Lettura 520MB/s Scrittura 390MB/s SATA3 Retail
The best SSD currently available, but 128GB seems small. What do you want on the SSD?
Programs and games that run from SSD are very fast, but games take up lots of space say 5-10GB for most titles, Max Pay 3 and Bioshock Infinite are 30GB each.
Getting a bigger SSD is a matter of price, how much do you want to pay. For Windows and games I would suggest 256GB if you can afford it.
Hard Disk Seagate Barracuda 7200.12 1TB 3.5" 7200rpm 32MB SATA3 ST31000524AS
7200.12 means 7200RPM, 12th generation. 7200 RPM drives are louder than 5400 RPM drives.
If Windows, programs and games are on the SSD you don't need a fast secondary drive. Western Digital Blue or Red series 5400 RPM drives are often recommended here.
VGA EVGA nVidia GeForce GTX 770 Classified Core 1150/1202MHz Memory GDDR5 7010MHz 4GB DVI HDMI DP
Cream of the crop of 770GTX cards. There are two versions with different cooler. The ACX cooler is more expensive and quieter than the stock cooler. The MSI 770GTX with Twin Frozr cooler is a little bit quieter than Evga's ACX cooler, but not by much. The Gigabyte 770GTX with Windforce 3X cooler is as quiet as the ACX but runs a little cooler.
I have an EVGA card because you don't void their warranty if you replace the cooler, which I did. If you keep the stock cooler the MSI is just a little bit quieter than the others.
4GB vs 2GB: I have a 4GB card and recommend 4GB cards. Few games currently need them, but I think that number will grow with XBone and PS4 ports. Is the extra cost worth it too you?
770 vs 760: 760 has the far better price/performance ratio. The 760 is fast enough for gaming at 1920X1080 resolution. Can you spare the extra money for a 770? Is the comparativly small performance bump worth the extra cost to you?
The cooler situation for 760 is exactly the same as for the 770.
