Advice on building a new rig

Fellow forumners, after seeing the results of my iMac from the benchmark. I have decided to build a PC rig just for FF14. But I am clueless when it comes to computers. I have done a bit of research on the internet and roughly know what I want. But I am not sure whether it is possible to build such a machine.

Can some of the technically inclined forumners give me advice?

Budget: USD 4-5k (including monitors)

Summary of requirements: Dual or triple monitor (I dual box) running at over 60fps on each of the 2 screen. 3rd screen is reserved for internet, movies etc. Compact PC casing with cool design. Ultra thin bezel monitors.

Casing: Some compact, with cool design, like the Bitfenix prodigy that I saw on the OriginsPC website, or Mac pro tower-like.

CPU: Am thinking of I7-3770 quad core. Do I need to OC it?

GPU: Is a single GTX690 enough to support 3 monitors? Or should I get a GTX Titan instead? Or should I get 2 x GTX680 with dual SLI? The problem is that compact cases seems to support only 1 GPU...

Storage: I only intend to play FF14 on this machine, and I intend to put both OS and FF14 onto SSD. Is 256gb enough?

Display: Am thinking of either 3 x 21" or 2 x 23". Would like to mount all monitors onto a monitor arm. Ultra thin bezels to create a seamless experience. Prefers monitors which are covered like a layer of glass and have similar richness of colors like a iMac. Would be good if webcam is included.

Cooling: Whatever cooling it takes. Would like the rig to be as silent as possible, below 35 db.

Mobo: No special preferences.

Sound: No special preferences

Speaker: No special preferences.

Movie capture: I would like to capture videos of raid. Are there any hardware that helps this?

Connectivity: Connect wireless. Adapter needs to be inside the casing.

Upgradability: Not required. I just need a high performing machine to play FF14 for next 5 years.
