Another vote for the Antec Three Hundred (Two). Done lots of builds with this one, cheap and good, if a little utilitarian.
Not too impressed with Fractal Design. They look good for the price, and seem well built, but both experiences were less than thrilling. The panels on my Define R4 rattle like a sonofagun, I would throw it away if it wasn't doing file server duty in a closet. I have a Core 1000, and the thing is incredibly noisy (or at least the stock fan is), the fan filter is impossible to clean as it doesn't really come apart, the side usb ports are so loose within a year as to be bordering on useless, and there are probably other things I've forgotten. Granted that is a mATX, but Fractal Design is in the "so close, yet so far category". My gaming box would be in the Antec 300 that's sitting in my garage if it would fit under my current desk.
