Why would you drop the Hyper 212? If you're going to overclock it's a necessity. I don't recommend SSDs on any sub-$1K build because you trade speed for space and you can really only get between a 60gb - 128GB and that will fill quickly. That's not a good thing. The GPU is where you'll notice the biggest difference on any build - not storage, case or anything of that nature. A good or bad GPU can often make or break the performance of any build. I don't cut corners to get things that I don't feel are necessity to the given budget - if the budget allowed for more room then an SSD would be appropriate. On this build - it isn't. You can always get one later.
The Ram G Skill posted has a taller heat sink on it and is more expensive. Some people think that these heatsinks improve the overclocking of RAM or keep them cooler, but to be honest i have ram without heatsinks and even overclocked they do not get hot enough that i can't touch them with my bare hands, so i do not think the heat sinks or fans for ram are very necessary. However, a lot of people like them. Also, he linked 1600MHz ram and i linked 1333Mhz ram, so his were a tiny bit faster.
Yeah but you're not going to notice the difference between 1333 and 1600 - your motherboard by default runs at the lowest speeds and timings it can handle. Only in the hardest core overclocking circles would you, but even then overclocking your RAM is never a good thing and can actually fry your build if you're not careful. I definitely agree that the tall heat sinks don't do anything but if you want something low profile go with this: http://www.newegg.com/Product/Product.aspx?Item=N82E16820148543
