Use
this for your motherboard, I've built with it a few times and it's very well made, seems to have good layout as well as plenty of features. It's also the highest rated motherboard on newegg
Use
this for your ram, it's faster (same brand) and it's pretty much the same price, also a reasonably low-voltage kit. I could recommend something more expensive but this is a very good value as is.
Use
this for your HDD because peer pressure. You could also look into getting a 120-240gb capacity SSD if you've got more to spend.
Use
this for your power supply, pretty cheap, gold rating, good reviews. You probably don't need all 1000W but it's a good value and a little extra capacity doesn't hurt, especially if you might overclock.
Use
this for your 780 ti, it's pretty much the same thing but with a slight factory overclock and an aftermarket cooler, for only like $10 more
