Btw, my case is similar to your second case picture (Cooler master haf 922), for your first case picture with the dividing plate just above the psu it would obviously make no sense to mount the psu with the fan towards the inside.

Now you mention it ... I'm not sure if the PSU fan top (bottom?) exhausts or extracts? ... for sure it has a fan that exhausts out of the back of the case so I reckon you are right ... it intakes cold air from a hole in the bottom of the case and exhausts it out of the back ... no hot air exhausting into the case in my example and I guess this is why my Corsair Obsidian 700 case is designed this way ... its supposed to be for dedicated PSU area's, water pump area's ETC .. mostly a lot of guff I reckon?, but the bottom line is my internal case temps are lower on the I7 2600K rig than the I7 920 rig and the PSU certainly does not overheat.

Cheers.
