First of all, can I have a fanless PC if the cooling on the cpu and ghx card are passive?

If no, what is the quietest case out there? Fractal r5?

Thanks alot!

Depends what sort of specs you want, it's totally possible to make a silent PC but if you want high performance it is a lot more difficult. It's a lot easier to just make a very Quiet PC using quiet fans and components. Even if you do use passive coolers if you don't use a case fan the heat can just build up inside the case. An older article here that might be of use http://www.tomshardware.com/reviews/silent-pc-gaming-performance,3435.html and a silent case review here http://www.tomshardware.com/reviews/hdplex-h5-fanless-computer-case,4503.html

This was my plan


3770k(already have)
Thermalright ultra extreme (passive, already have for 775 socket, can't find 1155 socket bolt thru kit, so using stock cooling atm, so possibly buy another passive heatsink)
Z77 extreme 4 (arleady have)
4x4 DDR3 ram (already have)
1tb hard drive (going to switch to ssd)
Gigabyte GeForce GT 730 Passive DDR3 64-bit HDMI 2GB
PSU (already have but it has a fan, probably just leave it)
Fractal r5 (not sure on the quietest case on the market, but then if I have a fanless setup then case doesn't really matter, if I leave the panels open?)

I plan to play low demanding games like League of legends and settlers 7.

You still need to have air moving through the case, or you will over heat. The easiest way to make a PC either Very quiet or next to silent is when selecting a case, make sure the fans it uses are the largest you can get. Forget about the smaller 80-90MM they rev to high.

Silverstone cases for example normally come with 120-140mm front fans. With Larger fans they spin slower make less noise ( or any at all) and stillcool. You can also get speed controlled fans if you want.

These cases here are just one of several options I use all the time when doing builds. http://www.silverstonetek.com/product. (http://www.silverstonetek.com/product.php?pid=352&area=en) Click on Featured Photos tab and you will see the front fan.
There's been more than once I've had to actually look to see if its going as cant hear any noise, esp if the OS had turned off the screen, only other sign is the LED's glowing.

Also make sure any cabling is tucked away and tidy helps with air flow.

I'm with dugi on this.
Go for quiet rather than silent.
You need to get the heat out of the box.
My current gaming system is the quietest I've built so far.
But it still has six fans plus power supply.
You don't need them running at full noise all the time.
In fact three of mine rearly run at all.

Ah wainui, I can see I'll need to speed up my repplies

Could change the case fan/fans for a quieter one with speed control options

Recently had a Board go in a HP desktop and with the replacement lost control of the case fan speed that was inbuilt with the old board and was unable to control with Speedfan,replaced the case fan with Noctua NF B9

http://noctua.at/en/nf-b9 it had 3 speed options which i have running at the higher speed and is virtually inaudible ,only the power supply fan can be heard

There's only 1 fan in this, the back fan which came with it, and I can't even hear it.

This is a silverstone case. I think it takes a front fan. (120 or 140mm). But there's no outlet on the front

But it can take 2 on the side and one at the back

Only downside to this case it it's matx and there are no bays at the front. Only a hidden 5.25 for a dvd / whatever

Only reason I got it the mobo is MATX, the PSU is on the bottom, it's got 3 places for ssd's and it hides the wires (there's not a lot in it anyway), since the PSU is modular

My gaming PC I built for performance turns out to be almost silent :) Just good luck though. I have a Corsair mATX case with a 140mm fan front and 120mm rear. The front fan is a low RPM quiet fan and the rear is connected to the motherboard header using the BIOS fan profiles to control it. The CPU cooler is the venerable old Hyper 212 evo also controlled by the motherboard and I have a gigabyte GTX980 using the Nvidia reference design. All of this is capable of cranking up the fans and making some noise but it cools so well that it never happens. What I like though is even though it's very quiet if something does get hot it can compensate, and I'll hear it and know that it's happening.

To hear my PC I have to turn the sound off and listen carefully, if I stick my head under the desk where it is it's a little more obvious. This is my case http://www.corsair.com/en-us/obsidian-series-350d-windowed-micro-atx-pc-case bought for much the same reasons as Speedies comments. This one does have a couple of front drive bays though, just not where the graphics card goes.
