building a new computer

So, I finally broke down and spent some money to upgrade my aging system, it has done me well, but the old Intel Q6700 quadcore 2.6 just isn't cutting it anymore..
I bought the I7 3770K, ASUS Sabertooth X77 Mother board, EVGA GTX670 FTW graphics card.. I decided to keep any other parts (HDDs, DVD, CD drives from my old computer since no significant improvements that I know of have happened in the last few years. I'm thinking this should tide me over for a couple years, since I do plan on buying another GTX670 FTW as well
I still need to get an SSD drive but that will be later
I am in the market for a new tower,and power supply and I really don't know what I want, I know I want one that has a lot of space to work in and I want to make sure I have enough power that I don't burn something out.. so If anyone has any Ideas, or has a case they are using that they really love I'd like to hear from you.
