This rig was built for the purpose of running Finite Element Analyses 24/7 for my thesis on Dynamically Installed Anchors. The SSD, Graphics Card and Optical Drive are carried over from previous computers. The software does not support General Purpose GPU acceleration for explicit unsymmetrical analysis and therefore a powerful graphics card was not really required (The GTX 970 is for occasional gaming). As the computer is running 24/7 and data loss is extremely undesirable, I chose a solid power supply that was able to deliver continuous clean ripple free current and went for a raid 10 (Speed and Redundancy) storage configuration (as one job takes up ~80GB) and an SSD boot drive. I plan to overclock mildly but want to run several jobs before doing so to ensure everything is working the way it should and ensure thermal compound is making good contact.

The good: - Fractal Define R4 case is quiet as well as one of the rare few cases that do not appear cheap or overly compensating - EVGA Modular PSU is great, high quality cables good layout/length of cables - Noctua NH-D15 is quiet and seems to effectively cool CPU

The Bad/Meh: - The Raid 10 array of HDDs and SSD boot up drive was annoying to setup, it required the bios to be set on RAID and only the SSD to be plugged in without any of the Hard Drive plugged in during the windows setup. After that reboot into RAID bios (ctrl+i) to create desired raid array. Boot into windows and format RAID volume using disk management as a new drive. - Onboard Audio was very average (would prefer external DAC) - Fractal Fans are a little noisy but not unbearable - Memory colour is mismatched with motherboard (Dam those skylakers eating up all the DDR4 stock!!) - Noctua NH-D15 is soo big that it touches the graphics card when installed in the first PCIe Slot!

Future Possible upgrades: - GTX 980 Ti - SM 951 SSD or Intel 750 SSD - Noctua Industrial PPC 140mm Fans (Undervolted for silence) - Intel Core i7 5690X or Intel Xeon E5 2699 v3 (18 core CPU... ok maybe not depends on how impatient I get with all these analyses)

Thanks for checking out my latest build!

Part Reviews


Best value workstation CPU, only main difference is PCIe lanes between the 5930K. When utilising all cores it will not turbo to max 3.6GHz and only to 3.4GHz (But can be overclocked readily).

CPU Cooler

Extremely quiet, extremely effective cooler (idles in mid 30 deg when running on normal mode and mid 40 deg on silent mode and tops out around 60 degrees under load [Non OC]). Has cut outs for the ram to clear large profile ram and movable fan placement. The cooler is heavy and so big that it will touch whatever is in your first PCI slot and can be annoying if the first slot is the only one running in 16x.


Very basic, plain X99 motherboard. Only 1x PWM fan control for CPU and only 1x PWM fan control for chassis fa. If you install CPU with 28 PCIe lanes (as I have with the 5820K), only the first slot will run in 16x and cannot be allocated to other slots. This board also only has 2x PCIe 3.0 16x, 1x PCIe 2.0 16x and 1x PCIe 2.0 1x slots and therefore no quad SLI/Crossfire Support. Onboard audio is pretty average and there is no onboard WIFI, bluetooth additional raid controllers (only Intel raid controller).


Great ram! Good value! maybe the latency is on the higher side but not much to complain or talk about here.


Great value Sata 3 SSD, great performance compared to competitors only slower than the Samsung 850 Pro series and obviously PCIe ssds.


Great value! Decent performance especially in Raid 0 or 10!

Video Card

Really decent performance, great looks with the blue LED "WINDFORCE" logo as well as relatively cool card, no fanless mode (Can be bios hacked and very easy), beware this card is extremely long and some midtower cases and most matx or itx cases may need to lose drive cages fans etc to fit.


Really quiet case, very minimalist design (I like!), easy to build in with grommets and cable management spots everywhere, great accessories (e.g. rubber mounts for Hard drives and fan controllers and plenty of sound dampening). But this case is heavy and only two 140mm fans are included.

Power Supply

Great power supply, great value and eco mode allows you to have absolute silence from the PSU during low loads, light gaming and idle. Highly recommended!!!

Optical Drive

It's an optical drive, it works, it writes and reads and makes loud zinggggg noises.

Totally unrelated to computers but as an engineering student myself why are you running FEA 24/7? haha also sweet build.

Lyonisk submitter 2 Builds 4 points 44 months ago

Thanks for checking out my build! I'm doing my thesis on Dynamically Installed Anchors and i'm using a Finite Element Analysis method called Coupled Eulerian Lagrangian method (CEL). CEL combines the soil behaviour as spatial coordinates allowing it move through the mesh freely and the anchor as Lagragian which means the mesh will move with the material. Using Lagrangian for both with compromise the mesh and using eulerian for both will lead to numerical diffusion. This method is computationally expensive even analysing a simple design for just installation/pullout may take days (When I was using my 4690K gaming rig http://pcpartpicker.com/b/npkTwP).

Interesting I have only just finished my freshman year so I wasn't quite sure why it would take that long. At my internship we do FEA on our parts but it must be far simpler as I don't think it takes that long.

Depending on what type of analysis you run it may take 15min to days even months for some people. I was freaking out when I found out an analysis took more then one day it made me realise I cannot cram as I usually do anymore!

14ewest 1 point 44 months ago

Haha I always try not to cram at the last minuet but it always ends up happening.

I already upvoted, $1343.00 hmmmmm, anyways, enjoy and good luck with the thesis, I could love that case if it had a windowed side panel and what monitor is that in the pic with the Big-hero wallpaper ??

Lyonisk submitter 2 Builds 2 points 43 months ago

Yea the price is irrelevant cause I carried over bits and pieces from other PC's the monitor is the Dell U2414H really nice slim bezels I got the background from Justin Maller's website! Since the PC is running 24/7 I went for the non-windowed side panel to keep the noise to a minimum...

breakerion 2 Builds 1 point 43 months ago

Thanks for the info, I dislike Justin Maller, had a little argument with him years ago since I was newer than him in art and he was a little arrogant on me, but that was long ago, check my stuff at breakerr.deviantart. com and gotcha about the windowed version, Gonna check that monitor review now :D Cheers!!

Thanks mate, I think it's just the giant noctua heatsink! Project Boreas looks great and setup looks awesome!
