Save yourself some money and get a smaller SSD.

This way, you have more money and can invest into secondary storage. I have a 120GB SSD right now and I just install all my software, keep some documents on it. As for things such as Steam, emulators, media files, misc files, you can store on your secondary drive and keep your SSD for your software and documents.
Just a heads up, if you're installing Windows, Windows likes to take up space depending on how much RAM you have. If you have 16gigs, it'll take 16 gigs of space on your SSD for hibernation mode. You can disable it like I did, or if you use it a lot, keep it. It also likes to put a file known as your "page file size" 1.5 times the amount of RAM you have. So 24 gigs will also infest your SSD if you don't change it. This is for people with low amounts of RAM, it'll move some of the RAM to a file in order to free some RAM up. Which is nice, but with 16+ gigs of RAM, you don't need a page file size quite that big. Things to keep in mind when installing Windows with a small SSD. As for your secondary storage, 1TB should do, unless you're like me and love to hoard movies and tv shows.

As for cooling your CPU, anything aftermarket is usually good for AMD processors. With no experience with Intel, I have no idea, though I'm sure a couple of people here can chime in. As for fans for your case, it comes with three, and honestly, that should be enough unless you plan on overclocking your CPU, which with Intel processors, is going to greatly increase the amount of heat it produces. Which in that case, you might want to look into liquid cooling. The case you picked out is plenty big to mount a radiator if you take that route.
Any standard DVD drive should work, unless you're wanting to get into Bluray, which I don't recommend because it's a major pain in the ass to get software to play Bluray movies. >_>
