I like the build. It's a good one. You don't need to change anything as it will all work and work well, but here's a few suggestions which you can take or leave as you see fit:
- Assuming you want the option of crossfire/SLI down the track, swap the PSU to this EVGA B2 850W for just $80:
http://pcpartpicker.com/part/evga-power-supply-110b20850v1 - you drop from Gold to Bronze, but it's still semi-modular and solid quality, but you save a massive $50 - dudeman is right though. You can easily get much lower PSU if you're happy to forgo the dual card option in future.
- You're spending a fair bit on a motherboard, which doesn't really get you anything other than some additional features which you may never need. Something like this Gigabyte Z97X-SLI probably has everything you need and is over $90 cheaper: http://pcpartpicker.com/part/gigabyte-motherboard-gaz97xsli. If you want more SATA, even a well populated board like the ASRock Extreme6 would save you $60:

- I assume you have a good reason for two optical drives, included the Blu-Ray burner? That's unusual, but fine if you need it.
- Price wise you are in GTX 970 territory which I suggest is better than a 290, especially at 1080p (the 290 starts closing the gap at higher resolutions). It's also lower power. I'm a big AMD fan myself, but even I have to concede that Nvidia has the better deal on the high end at the moment.
- You're sinking a huge amount of money into a wifi card. No way of getting a cable to your computer? Maybe look at a mobo with integrated wifi then? $85 is a lot on a wifi card.
Again, it'll all work and you've chosen solid components. Take or leave my suggests as you see fit.
