Side

Just for fun, here's a photo of the fan next to a CD. The side fan literally dwarfs any CD, and challenges the size of old-school LPs.

At max speed, the side fan is quite comparable to an actual desktop oscillating fan in both noise and air pushed. Here it is from the inside. The fan actually measures 230 mm, which is a little smaller than the declared 250 mm, but is still the largest stock fan by far.

Back

The back has a fan slot for a 120 mm fan or two 80 mm fans. The grill on this case is very thin with a lot of holes, which is much better for airflow. The holes are not large enough to stick a finger in, so safety has not been compromised here. There's also the standard PSU slot and rear panel.
