Description

This build is not for gaming. At all. It's a bit wonky too part-selection-wise, but I'll get to that in a bit.

Many who know me understand that I'm crazy about metrics and measuring things. I love to know all the details of the site, particularly how various parts of this site perform. What kind of database traffic, CPU/network/disk load, etc.

As we ramp up our benchmarking effort, I wanted to migrate from the 1920x1080 monitors we were using to larger 2560x1600 monitors instead. (Those are the ones you see in my other build - the H630/Titan build.) So I had those three monitors available for repurposing - so the dashboard was born.

The Lian-Li case was originally slated for a mini-ITX build over a year ago that got mothballed. The Z77E-ITX motherboard was also part of that build. The G640 was one of the lowest performance LGA1155 chips I had on hand, so that's why that's in there. And it's also why there's a Z77 paired with that - otherwise having a Z77 makes no sense whatsoever.

The Crucial Ballistix RAM was the low voltage RAM we got for free from a bundle deal on Newegg. We had tried it in manirelli's R4 build, but it wasn't compatible with the AMD motherboard. Fortunately it worked fine in this build.

The M4 is recycled from an old benchmark rig, which we're upgrading all of the across the board to a larger and more modern SSD type.

I originally threw in a cheapo PSU and GPU I had on hand, but the thing was way too noisy, particularly as it's right by my head. So I threw in a 400W fanless Seasonic PSU and fanless GT640 (picked that one for triple monitor output while remaining fanless). The overall draw is so low that they barely get warm. The PSU ventilation is actually opposite of what you'd expect - with the venting open to the interior rather than the exterior. This is because, well, coil whine. You can't hear it until you silence pretty much everything else. But when you do, you can't un-hear it, and it'll drive you insane. Whhhheeeeeeeeeheheheheeeeee-bbzzzzzzzz-bzzzzzz-wheeeeee-bzzzzzz. I about wanted to scream. So I flipped it over, which hid most of the noise.

The top case fan is actually pretty noisy, so I disconnected it.

The only fan in the system that is running is attached to the H90. I wanted to experiment here with the H90 because it's a 140mm cooler that matches the front fan mounts, and simultaneously cools the CPU and provides a slight amount of airflow through the case for the passive GPU and PSU. I have it set on the absolute lowest setting in the BIOS, and it's essentially silent. CPU temps are fine, as the dashboard web views are not performance intensive whatsoever.

I've purposely obscured the screens as I'm not keen on discussing actual traffic, internal stats, and bits of source code at this point. :) However, what I've got up and running is a combination of real-time analytics, and real-time performance monitoring via New Relic.

That's right R2

A Liquid cooled 2.8 Pentium, now thats a first.

It's an experiment of sorts. I may switch it back to the stock cooler soon.

The dissipation on the G640 is so low that I can leave the radiator fan unplugged and just passively cool the radiator. However, the water pump is actually slightly noisier than the fan on the lowest BIOS setting.

A liquid cooled pentium, good on you sir, good on you. Update us if you can over clock that mother trucker.

Gj phillip looks awesome, funny how the case and psu is more expensive than motherboard and cpu. But that fanless seasonic power supply is that any good? Since I'm building something similar to this, a Silent gaming rig, with water cooling and need a silent psu, also look at a xfx psu that turns the fan off if it's not needed. But yeah, also found a silent pump or near to atleast.

But yeah awesome build good cable management and stuff.

But what exactly are you gonna use this for?

"EDIT" Dashboard pc didn't see that until i browsed all the pics

The PSU is working fine, but if you expose the ventilation you can definitely make out coil whine. Once you silence everything else it'll be quite apparent and really, really annoying. Short of arranging the PSU such that the ventilation on the top doesn't have a direct route out of the case, I'm not sure what could be done. I suspect that the coil whine is present in pretty much every PSU - it just happens to be accentuated when nothing else is loud enough to mask it. If I had to do it all over again, I'd probably opt for a mini-ITX system with a built-in CPU like an Atom or AMD E-xxx CPU. Then if I could swing triple-monitor with that somehow, I'd be able to run completely passively and off of one of those 100-150W hockey puck style power adapters.

about that psu in that case: superbiiz website states you can only fit 140mm long psu, but seasonic website states that the psu you used is 160mm. So who's wrong? :) Cause if the psu is really 160mm, basically it has the same clearance as a prodigy, which is sweet for a case of that size. cheers

This is such a cool build! It looks so cool! Enjoy it.

Case kind of looks big for mini itx. It looks like the manufacturer could have made screw holes for a micro atx mobo if you took out the optical drive cage and got a smaller profile fan

Bit late, but that's gorgeous.

Hey Philip! How much clearance is there between the CPU and PSU for something like a Cooler Master GeminII M4?

I would be looking to use a Silverstone ST55F or something similar with a short cable kit to keep things clean.

Hey Philip, any advice on the fanless PSU? I might get the Gold 400FL, and I don't know what setup to do with the little beast. TIA

What are the dell monitors in your pictures with the code?

1200$ For a build that probably won't even run crysis. +1 For creativity.

 
 
philip [Staff,Submitter] [9 Builds] 1 point 5 months ago

Hahaha, you think I built it for gaming?

 
 
Frostfyre [1 Build] 1 point 5 months ago

maybe

I'd highly recommend you fully read the description before commenting on the build then. It has absolutely nothing to do with gaming.
