Mmm... yeah. I'll overlook the strip dance unless you're an attractive woman.

Thanks for that man
One more question, when installing the PSU at the bottom, how do i place it? With the PSU fan at the bottom facing the bottom filtered vent or the PSU fan turned upwards??

That depends of what your cooling strategy is.......
1. If you want additional extraction of warm air, then PSU fan facing up.
2. If you want your PSU to be supplied with "cool air" and remove the PSU from the case cooling equation, then PSU fan facing down. This is the default design variant.

In the end, I would reduce it simply to the height of your carpet pile!!!
Long pile = lots of dust/fibers --> Let the PSU breathe clean warm air from inside case.
Short or no pile = very little dust --> Let the PSU breathe fresh ambient air.

Right. Since I have a wooden floor shelf on my desk, I keep my HX-850 fan side down. Kind of a pain though since I have to remove my S-Flex G to clean the filter...

I dont have a carpet on my floor just tiles. Also lots of dust cos Iam in the tropics.
But thats what the filter on the intake is for right?
Since there are already pleanty of exhaust fans in the case, maybe I should install PSU fan-down? what ya think?

PSU fan down is the best choice!

I've put a Yateloon High speed 2200rpm there. But only because I had a spare one. I will be undervolting it anyway.
In my opinion the bottom fan should be less powerful so it doesn't grab much dust from the bottom and not deprive the PCI cards of some air. Noctua shud be fine.

But it does have the dust filter.
For me the GT is cheaper thamn the Noctua.

Dust filter isn't be all do all. There will still be dust coming in. Very fine dust so to speak. Since that part of the case is too close to the ground, I wouldn't want a fiery fan over there. Even if you put such a fan there, because of just how much clearing space there is, it won't be drawing a ton of air anyway. The air flow would be constricted. You need a fan that is as smooth as a gentle breeze. GTs will be fine too. If you can undervolt it using a resistor wire, that's even better.
You could even get Zalman F3s. They are pretty smooth but can turn out expensive. They do come with a resistor wire so you can have them run at 1000rpm instead of the rated 1800rpm without using the resistor.

I'm interested in the new Asus Rampage III Extreme mobo for my new build. Since my ATCS 840 is currently in transit... I was wondering if the Rampage III will fit? I thought I read somewhere that the Rampage III needs a case with 8 expansion slots.

What if I'm not going to Tri-SLI or Tri CrossFire? Do I need to worry that the motherboard will not fit with the PSU mounted on the bottom? Thx in advance for any info!
