Maingear Vybe Stock - Worth the buy?

That price of $2014, really is a bit steep. If you build it yourself with all of the top spec equivalents to the parts you have here, without a monitor it would cost you only $1629 (that's with parts worth $100's more than the ones here) on NewEgg without tax and shipping & handling. However if you do insist on buying this rig you will need to beef up that graphics card to maybe an AMD Radeon HD6970 2GB. And also you should have a lot more power on tap for a gaming computer than 520W even if SeaSonic is a great brand. So i'd get at least 600W, maybe 800 or 850 is you're planning to upgrade in the near future or if you are thinking about overclocking your system.
