I have just got both of these today as i was bored of my other case and psu. The PSU is mounted the same way as normal as if it were in the top of the case i presume? 120mm downwards. But how can the 120mm draw in air if i do not mount the case on the castors? I thought it would have mounted with the fan facing upwards? I dont know if its just me but i thought that how the PSU is supposed be mounted is stupid? Is it possible to mount it the oppsite way?
