Half the height; half the calories
On the back we can see that the half height PCI slots are kept locked down by a single screw clamp style device. Since this case is less likely to have you swapping in and out half height graphics cards every 12 months, I doubt this will be an issue to anybody.
Removing the power supply, we can see the exhaust fan mounted to it to draw cool air through the sealed enclosure; this is often much needed in small cases due to the thermal build-up that occurs with prolonged heavy power draw.
You might be wondering (as I was) what the maximum clearance for heatsink-fan units is inside the case. Well, you can see from the ruler, there's 80mm to the base of the case to the CD-ROM tray and approximately 60mm if you plan to put in a card reader or some other bay bling.
