Quiet and powerful computer for the home (server + build server): assemble it yourself or take it ready?

Question

Iron

We need a machine for now and for growth, which would act as a server for the desktop OS (with LAN access from a thin client), a build server and a web server for experiments. That is, the machine is required to pull modern OS and software for business tasks. I don't plan to play. Connect input / output devices to the machine - too. I want a box that can be put under the table, connected to the router and, if possible, forgotten.
The main criteria are the ability to read quickly when it is required, and low noise when it is not required. The speed of the calculation is probably at least a 4-core percent and at least 16 gigs of RAM. Low noise - it is very quiet, so that at night in a quiet room from three meters the car could not be heard at all.
Based on the above, I ask for advice on how to put my Wishlist into practice. If you take a finished car - which one? If you assemble it yourself - then what components should be considered?

Answer 1

I don’t see any problems to take a regular computer and just pick up a normal tower-type cooling with 120 or even 140mm fans.
A lot depends on what video card you put in. It is desirable with cooling for three fans and set msi-afterburner to the minimum speed at idle temperature.
Accordingly, the case is normal, but the cooling and the regulator - choose:

In the BIOS, set the speed control from the temperature. If it's not quiet enough - then:
buy a speed controller. Plug in and set up.
And supply the system with a 600W FSP\Chieftec\Aerocool power supply. So that it works in a more gentle mode and does not torment with its fan.
As a rule, this is enough.

Answer 2

Collect yourself. It will turn out somewhere to save on the case and components, but to pick up good cooling elements. And be sure to take an SSD under the system.
Or look at the Intel NUC, Zotac platforms. Perhaps they will, although it is not clear what you have with hard drives.

Answer 3

I'd go for a fanless system on the latest i5+ SSD SOCs. Maybe in terms of performance and not very good, but it should be enough for the stated goals, IMHO.
But the silence is absolute (only power converters can sing / hiss at heavy loads).

Answer 4

The budget would be indicated or something ... and what does powerful mean in your understanding? I'll tell you about my understanding...
If I advised myself, it would be Xeon E5-2683 v3 . 14 cores, 28 threads, 2GHz stock, can be overclocked to 3.1GHz if desired. The issue price is 20k rubles on Ibee. If I could now sell my i7 5820 and my mother in my city, I would take it. If possible, you can take a two-pronged mother, 56 threads ... There will be a really powerful server. In overclocking, the 6950X breaks in multithreading, and, accordingly, it will build from the heart.
From the silence, you will probably have to take dropsy and a power supply unit from the upper segment, which does not spin without load, because all the coolers are buzzing.

Answer 5

Here you have to collect yourself. Because If you don't need a video card, then the task is simplified.
What you need:
1) Quiet and high-quality power supply 550 watts. Here you need to proceed from what is in the stores where you will take the kit, according to the existing models, you can see reviews on noise and testing.
2) Processor i7 or i5 commensurate with the budget. There are models with an index s, they have lower performance, but also a lower thermal package, but I would take a regular processor.
3) You need an air "supercooler", such as thermalrigth macho or similar.
4) The case and cooler need very quiet fans. I recommend Noctua in size 120 or 140, rpm 800 - 1200. One for the cooler, one for blowing. If there is a normal railway, one for blowing on it. Also included are resistors to slow down the fans.
5) SSDs are silent, but larger volumes are expensive, on the other hand, assembly on ssd will be faster.
6) Case - you need a case with a lower PSU location (preferably), there are special options with sound insulation (like corsair). It is necessary to check that the cooler and fans are getting up.
7) You can also buy a device for manual fan control in the case. This will probably turn off the valves.
In general, the task is quite feasible, but if you need a powerful video card, then difficulties may arise.
