4 get a better power supply.... clean stable power is super important for a stable system http://www.newegg.com/Product/Produc...82E16817703009
5 consider moving up to 8gb of ram
6 go with a p35 or x38 based mobo (unless you want to do SLI)

All of these things will give you a better system for less than the price of the qx6700

Also I have the antec 900 case and it is great...
1. dont bother with 8GB of Ram, its a waste of money and by the time you actually need 8GB of ram DDR3 will be mainstream and time to upgrade again.
2. that PSU is sufficient, I prefer Corsairs though (520W version is plenty unless you intend to OC a lot then go with the 620W)
3. I also have the Antec 900 and love it. lots of airflow and very qiuet due to the size of the fans. A bit on the heavy side though so not the best for LAN party travel.
4. Your right on the motherboards, was just sticking with an SLI board for that futureproofing thing since even though WoW doesnt there are some games that are pushing the envelope on GPU needs these days.
