The chassis shown is the Cooler Master CAV-T03-UW, which is solidly built and relatively cheap at $60. It's lying on the chassis on top of the drive bays. I've also taken the power supply out of the box and laid it inside the chassis, shown in the upper-right of the photo Note how the power supply has the fan grill exposed toward the motherboard. That is the orientation you want.
