Complete new build for development and gaming, less than 2000$

Hi,

I need a long-term working build with good gaming abilities for a budget of 2000$ max. Should be able to run virtual machines (hence the 16GB RAM) as well as two separate OS Win7 + linux (hence the two ssd) and use two monitors (I already have one). I will probably end up overclocking the CPU later but it's not a must have.

I would really appreciate a quick review of my choices to make sure I haven't made any obvious mistakes in terms of compatibility, if I forgot anything or if there are better choices than mine. I basically need everything except a mouse...

Again thanks for your advice and for any input on this configuration.
