i point you towards this paragraph:

if you look at the picture of the rear of the case, you will see four mounting holes between the PSU and the mobo backplate, this is where the crossflow fan is mounted, not over the 5th blank PCI slot.Originally Posted by Review
the review implies that the crossflow fan fits over the 5th blank PCI slot, which is something i did indeed suggest to SST, but as far as i know they have not implemented.
it could be that SST did implement this, but your picture doesn't show any mounting holes for the crossflow fan other than where it was originally intended; between the PSU and mobo backplate.
hope this helps.
p.s. any idea when scan will get stock of them?
