My questions are:

-Would everything fit in this case
-Should I get a Full Tower Rosewill Thor v2 instead of the Fractal Design Define R4
-Would I be able to overclock the CPU to about 4.5 GHz
-Should I get the 780 or wait for AMD's 9000 series cards
-Tips/Changes?

FYI: I am getting the CPU and Motherboard at MicroCenter so for both of them it will cost $398. Making the cost of the computer really $1578.49
