Your motherboard is a bit pricey. You could drop it to the Maximus Hero. It's not like you are going to be looking at it with its "Thermal Armor" in the windowless Source 220 anyway, which is the main reason people buy the Formula.
And your PSU seriously needs to be of better quality! The Corsair HX 750 recommended above is good, I personally have a TX850M and it works great and I got it for ~$100.
