I made a horrible mistake and bought Crysis3 for 5€. The AMD 7850K just didn't seem to run it smoothly enough so I just HAD to upgrade.

Since I already had a picoPSU 160XT, I planned to re-use it and make low power set that would be more powerful than my previous one. First, I planned to use my old Cooltek Mini Cube but it was too small for a quiet graphics card.
The parts are now:

Lian Li PC-Q01
Gigabyte Z97N-Wifi
Pentium G3258 (OC'd to 3,5GHz and undervolted ATM)
Arctic cooling Freezer 13 Pro with Noiseblocker eLoop PWM fan running 430-660rpm.
EVGA GTX 750 with AC Accelero S1
G.Skill Ares 2133MHz 8Gb kit from my old build
PicoPSU 160XT from my old build
Samsung 850 Evo 250GB SSD

Looks good to me.

I lined the case with some sound dampening foam. It's not too dense, but it surely does help. That side panel actually extend to the top and is just one piece of aluminum. Makes it really easy to work with this. There's some foam over the cooler and under it to create this "wind tunnel" effect. All the air the fan blows should go straight outside while creating negative pressure inside the case drawing all air from the bottom of the case and through the GPU cooler.

The case isn't actually deep enough for Accelero S1 cooler but since I already had one lying around, I just cut about 15mm off the end and barely got it to fit.
That black thing hanging from the back is the power connector for PicoPSU. Didn't bother drilling a hole for it.

Image
That AC cooler is pretty old and I used it with my old i3 2100 build a few years ago. I've never used the original fan but now when I tried it, it didn't even work at all.
Swapped that fan for a Noiseblocker eLoop PWM fan. It has the best sound of all fans on low speeds (no sound at all). I've tested tons of fans and this is the best so far.
I had another fan on the bottom but after some stress testing I found out that it isn't actually needed. There's plenty of airflow for this build like it is.
That fan runs at about 420rpm on normal use and about 660rpm while gaming. Speedfan controls the speeds.

The temperatures are better than expected.
CPU idles at 37C and GPU at 30C (ambient about 23C ATM)
Load temps are about 65C on both. GPU maybe a bit lower.
Power consumption was about 120W under gaming. I could've overclocked CPU and GPU more to gain more power but I just don't need it right now so I left them at this.

I have to say this was quite a success as the computer looks good, is inaudible and plays games at good enough fps for me.

Pretty nice build, congrats.

Something that would complement it is a PSU cover, if you can find it, Lian Li Vented Power Supply Bracket Cover - Silver

Superb build. Lots of performance for such a small power footprint. That picoPSU is impressive.

That PSU cover isn't necessary. I'm not looking at the back of the computer after all. Airflow is better without it as well.
I guess I'd have to do something about it if I get a cat or something.

The PicoPSU is nice, but there have been a couple of problems with it. The adapter from 4-pin to external connector is really badly soldered. (the one that's hanging outside the case)
At one point the computer started to crash while gaming and I tested all the components and didn't find what's faulty. It was one of those ground cables that was loose from that adapter.
Soldered it back and everything worked fine.

Actually, the same happened just a few minutes ago again. It was the other ground cable this time. Just soldered that back as well.

Very nice build! It's pretty similar to mine in a Lian Li PC-TU200.

In my build I have the single fan in the front, blowing on both the cpu and gpu cooler (750 Ti w/ an S1 Plus). How does the graphics card do with no air flow?

Also one suggestion is to put some electrical tape around the pico-psu wire that you zip tied to the case. I didn't at first and started to see some scrapes and wear on the wire.

Nice. this has been my basic layout in most of my builds over the last few years.

No problems with the graphics card. It's simply amazingly energy efficient and doesn't heat at all.
While the card itself doesn't get too much airflow, most of the air that goes through the case comes from the bottom passing through the Accelero S1.
I could make a bigger hole on the bottom and put a dust filter there but I'm not sure if I should bother.

I guess I could've gone with GTX 750ti and a smaller case.

I see, I didn't notice you blocked off the front at first. I might have to try that with mine! Currently I can really hear the front fan when it speeds up during gaming.
