[quotemsg=13445112,0,1624384]Is it a reverse air flow design? Maybe air flows in through the back, through the CPU cooler, then through the power supply and out the bottom?[/quotemsg]PR said that the power supply was backwards, but I believe you're right. The builder needs to turn around the rear fan and CPU fan to use the PSU for exhaust. The PSU should be able to take the heat from so small a CPU.
