Is this a good gaming build?

Suggestions:

As mentioned above, are you intending to overclock. I do not see a CPU cooler so I would assume no. In that case you do not need the "K" model CPU.

PSU: A bit better PSU for same price. http://www.newegg.com/Product/Product.aspx?Item=N82E16817371016

HDD: The Samsung F3 drive has almost the same performance as the Black drive and this is 1TB. http://www.newegg.com/Product/Product.aspx?Item=N82E16822152185&Tpk=f3

GPU: For a little bit more a GTX 660 would perform quite a bit more. http://www.newegg.com/Product/Product.aspx?Item=N82E16814130826 This guy would perform VERY well.
 
I think it is good as is.
Samsung cut the warranty on their F3 to a miserable one year. That's not confidence-inspiring. The WD Black has a five year warranty; possibly the only [non-enterprise] drive that does.
The Neo-Eco is Seasonic-built. I don't think they know how to build a bad PSU. The BP-550 has reviewed well, but it is not better.
The GTX660 is a slightly better performer in today's games, but it has crippled compute performance, which may matter tomorrow, or for any other GPGPU tasks you may have (like bitcoin mining, if you're at all interested). If you think you might want something stronger, get a HD7870.
If you think you might overclock, get a $20 Xigmatek Gaia. It is up to 6db quieter than Crappermaster's similar models, cools better than the Hyper 212+, and is within a degree of the Hyper 212 Evo (this according to Frostytech.com); and it's cheaper.

Edit: Hmmm, I did notice the wireless card is only b/g, not n. Get a wireless n card; it's faster. Even if your current router only does g, it's cheap future-resistance.

Wait, is crippling a good thing or a bad thing? And what is bitcoin mining?
 
Something that is crippled does not perform well; think of someone with a crippled leg.
Wikipedia has a lot of information on bitcoins, an alternate, electronic currency struggling to gain traction. "Mining" bitcoins is a computationally-intense task that is well-suited to running on a GPU. nVidia GPUs use more electricity than they recover by "mining" bitcoins; some AMD cards excel at it. Whether it is worth doing depends on the exchange rate and too many other factors to predict. Read the wikipedia article and links for more information. It is certainly interesting if only as a theoretical exercise. The parasites will undoubtedly find a way to shut it down if it become significant.
