Hello! I organize an airflow in the odd pc case.
I drew a scheme for you.

Only four fans in the system:
CPU fan
PSU fan
GPU fan
and back case fan.
Sides of the case have no holes at all, only perforated segment near HDDs but it covered with plastic case layer.

I started up the pc and took lighter to test airflow with flame.
[/DON'T DO THIS AT HOME]

And doing so I saw air sucked in through the front holes and blown away from psu in very active pace, but back case exhausting fan seemed to have no clear blowing. Flame didn't bend away from the fan as it did with psu exhaustion radiator or (bent in) front holes, but shaked much in really random manner.

I'm unsure what to do. May be set the fan to pull in instead? But there is CPU fan right behind blowing heat away.
Seems like psu fan sucks so much (in a good way =p) that it pulls the air in opposite direction through rotating back case fan.
Or may be there are other reasons. Need your advice!
 
That's a strange case. What motherboard is it. I don't usually see the graphics cards to go above the CPU.

And you tested airflow with fire? I would definitely not want to be anywhere near you when you are testing. That is dangerous. You can blow up the whole thing.

Is there an opening at the bottom of the PSU? If so, flip it upside down so that the fan is pulling in air from the bottom of the case.

Thanks for fire warning (I put the disclaimer).

It's usual mATX motherboard turnd way around. The picture is just from motherboard's side.

No, the bottom is solid. What about the back case fan?
 
That's good, I guess. I'm glad you weren't hurt because if the PSU did blow up, you could be in the hospital by now.

The case is not very efficient in terms of cooling. You will need a rear fan because otherwise, there won't be much exhaust. You can buy a new cheap case that is more airflow efficient. Alternatively, you can replace the PSU with a fanless PSU.

Please can you elaborate alittle how fanless psu will help? Rear fan works it's just unclear how efficient it is.

p.s.: this is really odd case, so I would like to stick with it =D
