Processor (looking at either high end i5 or low end i7)
Graphics card (I've been checking out the GTX 660ti, so something in that quality/price range)
SSD Drive (I want to add a SSD of about 200GB for games)
Motherboard (I have no idea about these but with a new case I'm going to need a new motherboard since Dell is....Dell...)
