I'm considering moving to a case that is virtually identical to the one I have now, but with a fan outflow on the top. What do you think, is it worth the effort of the move?
Fan outflow on case top - worthwhile, or not?

All good points, but I might get the case anyway, and test it before further considering moving my system into it. I go through cases like water anyway, so I end up not liking it, I can just sell it to someone else.
a top blowhole exaust is the most effective fan in you case.
if you can only have 1 fan in your case, the blowhole should be it.

In my case, the power supply sits at the very top of the case, there might be a quarter inch of gap. So, the PS fan seems to do a good job of pulling the hot air away from the top of the case. In fact, the top of my case usually feels cool to the touch. But, if your PSU is mounted lower in the case (more likely, the case is just taller than mine...) and not pulling the air out of the top, than the blow hole can be a great idea. So, when you touch the top of your case with your hand, is it warm or cool?

its nice as it forces an air path past the drives, and well heat should go back and up through the case. with many cases theres a dead zone in the front top area.
noise isn't a biggy if you ues low rpm.
course some cases like the big antec/chieftecs are so well ventilated for most users its unecessary. but for cramped or older cases, adding a blowhole aiint'bad. esp those pos mini towers witht the sideways mount psus that block normal cpu air flow.
make sure u have pc located where sh*t can't spill in obviously.

I'd been thinking of getting this Dynapower Spiden 99BLS Black ATX Mid Tower w/ Window & 430W Power Supply, that's why I was wondering.
But for reference, the top of my current case does not get hot, so it may not have helped anyway. I specifically bought this one for the open slats at the front, so I could mount a 120mm Evercool aluminum intake fan in the front. And everyone loves the getto fab look

The fan on top is actually not a great idea if you have other fans on th back of the case in exhaust mode. Yes, heat rises on it own, but not when it is being pulled to the back of the case. If you try to exhaust from both the rear of the case and the top, then you will end up with dead zones of no airflow inside the case. If your case has exhaust fans in the rear of the case, then all other fans should be intake. All mechanical engineers on my staff agree with this setup.
So, the mechanical engineers on your staff have never heard of physics? As in hot air rising? I'd hesitate to mount a blowhole fan as an intake, that's for sure. Maybe changing the rear fans to intakes instead?
My post clearly says that hot air rises. However, it cannot rise when it is being physically pulled in another direction. And it has nothing to do with physics. Using the top fan for an exhaust fan would work well if it had the capacity and all other fans were set to intake. The only conflict may be the power supply fans, but they are usually not all that strong. Best setup is still exhaust to the rear, and all other fans being intake, since the power supply will be set up to exhaust.
Why not just cut the fan mount yourself? Assuming that there are no struts where the fan would be, I don't see why not. The cases are identical, save the fan mount, right?
Also, what an anyone says, regardless of how logical, cannot change facts. If a blowhole fan lowers your case temp the most, then it is the most effective fan.

Which has me thinking. If I get a de-hydrator couldn't I suck cold chicago winter air from outside into my case? After all, pushing 35* air through a HSF should cool a CPU/case better than 70* air, right?
I'm in San Diego....I'd have to mount my case inside my fridge, and there's just no room! :light:
