"When opening up the case the PC-A05N's unique internal layout can be easily grasped. Besides the motherboard being mounted against the opposite side of the case compared to most ATX enclosures, the motherboard is also flipped around 180 degrees so that the expansion slots are actually higher than the I/O panel area and CPU socket(s). This rotating of the motherboard is not the first time this has been done but can be seen previously in other models and those from SilverStone Technology. With this case's design of pulling in the air from the rear and exhausting at the front, the motherboard, CPU, and any installed graphics cards are to get the coolest air while the warmer air is pointed at the optical drive bays, hard drives, and power supply. While this case is small, an ATX motherboard can fit quite well inside."
