Given that the last 3" of that render looks to be just fan perhaps the oem is 12" single slot and the retail one is 9" Dual slot with the fan in a more traditional position.
Not quite sure why but I could imagine it would be possible that box shifters would prefer a singe slot solution - avoiding having to sell systems where a motherboard slot is unusable or form factor advatages perhaps.
Its looks like not as a single slot cooler, because there is a cooling channel, somewhere the air need to be go out, and the only exit in the cooler is the left side of the card.
Coolers what working with this schem its HIS iceQ3 or ATi reference x1950xtx cooler, all dual slot.
