Chieftec Dragon cases are great. While I don't personally own one, I've had the pleasure of building systems into a couple of them. They've got plenty of room for modding. Try adding an 120mm blowhole to the top, and side duct or fan to aid in either video card, or processor cooling. Another nice mod I've seen done is to replace the center portion of the front door with plexi, and add leds around the edge to make it glow.
