Case has bad cooling, go better instead for both a clean look and 4 fans.
SSD is fine but I prefer the 840Pro, and 2 128s in raid on a z77 build. That said, Plextor is my ultimate choice atm. It'd be a bit more expensive though so I won't really argue it but think about it. Raid doubles the r/w speed and iops which is nice as ssd degrades over time and starting with a 1000mb/s read is better than 500 3 years from now. Food for thought.
GPU is bad get this I would prefer sli 660s but it'd be about 100 bucks more for cards.
MSI motherboards come with OC genie which is a feature on MSI bios that make it extremely easy/stable to go 4-4500mhz on the overclock with 3 clicks if you are someone that is iffy about OC, it'd be a good board for you even it wasn't cheaper.
Funny... Just built my computer for the same game (FFXIV:ARR (2.0)). Here's what I suggest. I built nearly an identical system. The RAM is out of stock at newegg, and expensive at amazon, microcenter has it for $55. Supposed to be the most overclockable Ram. I'm sure you can substitute crucial, corsair, etc. Power supply is rock solid. Here's a review . That said, if you want to crossfire/SLI, it won't be enough (though I doubt you need to crossfire/SLI for those games). At that point, I'd suggest This or This .
That said, this is basically what I bought. I think a case is a personal thing. I got a Fractal Design Define R4 case. I put a decent cheap one on here, you can pick your own.
I'm waiting for a cable extender to completely put it together. The 8 pin is stretched over my GPU/MOBO instead of being routed behind. Send me a PM and I'll let you know what I think of it when I get it together this week.
