Question 1

Would a Corsair H100i be able to run with push+pull fans in this case?

Accepted Answer

Yes, there is plenty of room for a h100i. In fact, I think you should consider a different case. This thing is MASSIVE and is designed to have a ton of spots for radiators and lots of room for a custom water cooling loop. They have room for 4 x 120mm radiator at the top, and both bottom sides, the front has room for a 3 x 120mm radiator and the back has room for 1 x 120mm radiator. Thats a total of 16 x 120mm radiator, and you only need room for 2.

Dont get me wrong, this is an amazing case and I would tell anyone its worth the buy, but in your situation I just don't think you need something this big. I got this case because I needed room for a pump, hoses, reservoir, radiators, multiple gfx cars, extended atx motherboard, etc.

If you do get this case, I would suggest mounting that on the top. Its the best spot for a push/pull configuration as it has the most room for fans and a radiator..

And just to let you know, push/pull is a gimmick. If you have the same fans on each side, you will get maybe a 2-3% performance gain. Nothing noticeable. Think of it this way, if you get 2 computer fans, put them on top of each other and have one blow through the other one, it will not make it go faster. They are both producing the same amount of airflow. That is in theory however. The tiny boost in performance comes in the fact that the radiator will cause minor air resistance, so having one on the other side pulling helps reduce that resistance. But this is minuscule. The fans that come with those h100i watercooling system are rated really well. I would suggest using them in whatever configuration corsair suggests.

If you have any more questions about it, send me a message.

Question 2

Can I fit a triple or quad rad in the top of this case?

Accepted Answer

Just about any 3x120 (and some 3x140) in addition to loads of 4x120 will fit.  I have 2 4x120 Black Ice SR1's in mine right now.  You can fit a total of 3 quad radiators in this case as well as a triple in the front and a single over the exhaust fan.  Should you need that amount of cooling of course!

Question 3

How big is the cable management compartment?

Accepted Answer

Its pretty spacious. Big enough to fit tubing for WC builds as well. Plenty of space for as much cables as you could ever need and then some.

Question 4

will most power supply cables reach everywhere that they need to? i know this is a huge case, so im concerned that if i buy it then my corsair 800 watt psu's cables will not reach far enough.

Accepted Answer

The straight line distance from the center of a mounted psu to the top of the mobo is 20 inches. I have a Enermax Maxrevo 1500w psu from newegg and the plugs that came with it reach everything.  You can look up their lengths on here. The 24pin has plenty of slack but the wires to the 8pin at the top of the mobo are pretty tight.

On a different note, if your rig can be powered by 800 watts, this might be way more case than you need. I have 500 watts in video cards alone.

Question 5

Based on some of the reviews, people said the case had cheap plastic on it. How cheap is the plastic, and has it broken on anyone?

Accepted Answer

the hard drive holders are real cheep plastic when you try to pull out a hard drive they do have a tendency to snap off so be very careful pulling out your drive. i also found that the lower side panels when you open and close them be very careful they have a tendency to get out of alignment then it will hard to close because the magnets that hold it close wont touch the panel not to put down the case. I am very happy with my build using this case  but for the price you pay for it Corsair have not yet addressed this problems.

Question 6

Would a H100i GTX fit in this?

Accepted Answer

Yes, easily, along with anything else you can imagine throwing at it. If you wanted you could put three 480mm radiators, a reservoir and a pump inside and still have room to put a full size mobo, 4 GPU's, and a half a dozen HDD/SSD. The case is huge.

Question 7

If I put in an ASUS Rampage IV Black and a Hercules 1600 watt into this, would I still be able to fit a thick quad 120 rad in the bottom and a thick dual 120 on the other side?

Accepted Answer

Yea that should fit fine, although it might get a little tight in the bottom because you have to sqeeze the width of 2 thick rads, plus fans for each one. Then you also have to be sure there is room for a pump and hosing to fit down there too, so it could end up pretty tight.

I would reconsider rad placement for this case. A very popular choice for dual rad placement in this case is to have a quad (slim or thick) rad on the bottom side. Instead of putting the second rad right across from it on the bottom, it would be a good idea to get a triple rad and mount it in a push/pull config under the top of the case. That area has TONS of room for a thick rad and fans and wont even be close to touching your mobo.

Good luck with this case, you won't be disappointed! Its way bigger when you actually see it in person.

Question 8

Does this support dual power supplies?

Accepted Answer

Yes this case is fully capable of mounting dual power supplies. 
** Be warned that doing so would cut your options for radiators/fans. **

Question 9

What size fans can be mounted in the case?

Accepted Answer

You can mount 14 fans size 120mm and 1 fan size 140mm.

The case comes with 3 fans size 120mm on the bottom front and 1 fan size 140mm on the back.

There are mounting holes for:

* 4 fans size 120mm on the top
* 4 fans size 120mm on the bottom left
* 3 fans size 120mm on the bottom right

If you are liquid cooling your rig, you can:

* mount a 4 fan radiator on the top
* replace the front fans with a 3 fan radiator
* mount a 4 fan radiator on the bottom left side
* mount a 3 fan radiator on the bottom right side

The case is huge and very heavy. Be prepared. :)

Question 10

Power button..... where is it?

Accepted Answer

Center of the top bay front.  The top bay is a door covering USB and audio ports.  There is  a notch in the door that the power switch and lights sit in.
