May I ask where you got that case?
Yeah nicely moded, made me wonder where you will place the PSU. I still wonder, since the hot air from the psu exhausts right at the hard drive, not too good.
But nonetheless I still admire your build.
I don't think so. A PSU exhaust is usually where the power cord plugs in the psu, and that would be outside the case if you looked a bit carefully at the pic he posted. Unless he decided to switch the fan inside so they push the other way in the psu (which I would be intrigued to see anyone do), the fans are taking their air just under the HDDs and pushing it out the bottom of the case
