Link to all the files to recreate/modify Monolith

Hey everyone! I hope you are all having a nice day. I’m happy to finally be able to share my custom SFF case project, Monolith, with you all! It’s been months in the making, and it feels great to have turned my idea into something real. It’s also open source (yay!), links are down below!

The idea of this case started a little under a year ago during my sophomore year of high school, when I embarked on a journey to create a custom case. Some part of creating something based on your own needs was really interesting and appealing to me. I learned Fusion 360 from youtube, and after a few revisions (and a lot of swearing!), I had something I was happy with.

From the start, going SFF was a no brainer. I liked the challenge of being creative with space saving, building materials were cheaper, and I had most of the parts on hand. The pc is centered around a M-ATX board, Flex-ATX PSU, 2.5’’ SSD, and dual slot 750Ti. The case ended up being a little over 8L - not tiny, but in the same range as most SFF ITX cases like the Dan Case (to my knowledge, Monolith is the smallest M-ATX gaming case out there.)

I kept the design minimalist and cohesive. I love what Parvum does with their cases, and echoed a lot of that design ethos in Monolith. I even used their modding cubes and black screws for an industrial look and ease of use. The rear grill is inspired by Murderbox, and the side grills are a design that I haven’t seen too often (but like tremendously.) I also really like how the inside turned out as well - the SSD shelf does a great job of covering up the PCIe riser cable and obscuring the otherwise empty M-ATX board and makes the case feel tidy and compact. The name Monolith comes from the case’s sleek, tall, and thin design.

I lasercut all of the outer panels out of a single sided matte piece of acrylic at my local makerspace and am really happy I went with matte - the coating absorbs light and repels scratches compared to normal cast acrylic. The parts I couldn’t laser cut like the GPU Mount, Brace, and SSD mount were 3d printed using 3d hubs.

Probably the most time intensive part of the build was the custom cabling. Seasonic doesn’t publish their pinout, so I used the wiring harness that came with the PSU to create my own pinout. I integrated cable combs into the case for cable management, and used 550 paracord to sleeve new cables that I made from scratch. Since the PSU didn’t have enough 12v or GND outputs for my components, I had do a lot of soldering and heatshrinking. However, the end result was worth it IMO.

However, the build is nothing if it doesn’t work! The Noctua does a remarkable job of cooling the 7890K, and it maxes at 59C at stock speeds on Aida64 while being undervolted by .05v. The Fan RPM stabilizes at 2170 RPM, which is pretty inaudible. The 750Ti, well, runs incredibly cool and quiet like every 750Ti. I run it at stock speeds, and the GPU chamber of the case stays cool to the touch. As for the PSU, I’ve heard the fan can get very loud, but there was never enough system load when I was playing games for it to spool up.

Thanks for taking a look at my project. You can follow this link, where all of the DXF, STEP, and Assembly files can be found for you to make Monolith/remix it. I have a lot of new projects that I’m working on, and can’t wait to hopefully show them over the next few months! If you have any questions or comments, please let me know! Have a good one!

Dude, you get better at this and you can start selling them.

ecogamer414 6 points 18 months ago

I would buy that.

maggotshero 10 Builds 1 point 18 months ago

An ATX power supply version would be awesome.

appleihackgeek 1 point 18 months ago

Why not SFX? ATX PSU would pretty much double the size of this case.

maggotshero 10 Builds 2 points 18 months ago

I was meaning that for if he wanted to make a standard ATX version of this case. I think it'd be pretty popular, with it being the standard and all.

Drokovian 1 point 18 months ago

yeah but it wouldn't be nearly as compact, nor would it be small, making the niche part of this case go away - what makes it so desirable.

evert7877 2 points 18 months ago

Haha, indeed

UntamedShadow 3 Builds 8 points 18 months ago

My gosh, this is by far one of the greatest builds I have seen on this site. I too am a big fan of the SFF itx/matx cases. I've been designing my own case as well while looking at cases that I like from Fractal, Ncase, Project Orthus, Cerberus, In Win, Jonsbo, Lian Li, Phanteks, NZXT, Corsair, etc (Long list of cases that I love!!!!!). The only thing is that I never found one that suited all of my needs, this case would have something I like and the other case would as well. Hopefully soon I will be able to finish my project and share as well.

Two big thumbs up from me as this is not only a project I can relate to but respect as well.

Thanks for posting and I hope it serves you well.

Thank you so much! I wish you luck with your project, and can wait to see it!

Needs to be featured, +1 great work!

PrintBuildz 2 points 18 months ago

Already featured, so your wish came true!

"Energy Drinks and lots of swear words"

hahaha...love it! =D

yltq227 2 points 18 months ago

While reading through the description, I was really confused on why you had an i9 7890k in an micro atx motherboard with a 750 ti and then I realized it was an amd a10 7890k.....

L2112Lif 2 points 18 months ago

Amazing cable management, that's so clean. Super important for a SFF build, you should be proud of your work.

ScottCisney 2 points 18 months ago

Hello Colinray it looks great, I did notice one thing while looking at your pictures that the ram on the left is not fully seated, hopefully this is not giving you any issues.

masterkickass7 41 Builds 2 points 18 months ago

This Build is beautiful but my only question is why did you pay $250 for a 750ti

Longshanks 1 point 17 months ago

He didn't put in the price he actually paid. It is just listing the part and the current retail price. It'll keep changing.

EricB93 1 Build 1 point 18 months ago

I am in LOVE with that case. I love SFF cases and would be ecstatic to have a case like that. Great build!

Drente 1 point 18 months ago

Thanks for the link Colin. It makes a lot of sense this layout.

Superb!!!

So awesome!

lightroomuser 1 point 18 months ago

I really like the case! How did you produce it? Did you use a local CNC or send it off to a service. If you did the latter, what service did you use?

thebutterknife 1 point 18 months ago

Just curious, why make the space for the matx board? It doesn't look like you can use more than one expansion slot. Was it extra ram slots or other board features not available on itx?

Sweet looking case. You've done a great job with the design.

gugu96 19 Builds 1 point 18 months ago

FANTASTIC case! At first I thought "oh a new NCase?" and then I saw the work.

evert7877 1 point 18 months ago

Very cool little machine you've got there.

sq_sqd 1 Build 1 point 18 months ago

Wow. That is a truly beautiful case!

Yahtadi 1 point 18 months ago

Ohmygad, a frigging goosebumps!

WirelessCables 1 Build 1 point 18 months ago

Very cool to see a custom case like this. The only thing I can suggest is to throw in a couple of dust filters, but you probably have plans already. This deserves a feature. +8 ;)

Gentleman00 2 Builds 1 point 18 months ago

I really like the sleeved cables. Good job. +1

Drokovian 1 point 18 months ago

I'm really glad that you made the files to recreate Monolith public because while we all would've been fine with you sending out manufactured parts, it would be also interesting to see other people attempt their own modifications and improvements to the original.

nammerbom 1 point 18 months ago

If you ever make a second version of this case, you should bevel the edges of the case wall so that they fit together more flush. Neat project!

BlueSonata 1 point 18 months ago

That is one of the coolest cases I've ever seen.
Great job man I can tell that you put a 3D printer's amount of time and effort into it! +1

Faasos 1 point 18 months ago

you are ******* kidding this is great

TMoneyMoney 1 point 18 months ago

"Energy drinks and lots of swear words"

Hey sweet, I used the same custom part as you! +1

SHD_Agent 1 point 18 months ago

It looks awesome, I would even consider buying one if you were selling them.

Pure24 1 point 18 months ago

Great work!

Mtthwmths 2 Builds 1 point 18 months ago

That's an awesome case! Great job, I've been hoping to do something similar but using an ATX PSU. Like the cable combs in the case, that's a really cool touch. :)

"Energy drinks and a lot of swear words"

I chuckled. +1

appleihackgeek 1 point 18 months ago

How loud is that PSU? Also, why go with an MATX board when you can't use the other PCI-e slots? Seems like ITX would be a better choice, and give you more space to either decrease case volume or have more drives (like a 3.5" in addition to the 2.5")

samkomatus 1 point 18 months ago

The cable management is awesome dude. +1

xTHExRADxREXx 1 Build 1 point 18 months ago

this is a great build but i gave 1 question y not go with a water cpu cooler instead of the air one

Sentinel3.14 1 Build 1 point 18 months ago

I assume budget. And it would be really hard to fit and manipulate a aio or even custom in that space.

xTHExRADxREXx 1 Build 1 point 18 months ago

tru

Hey, I'm doing an acrylic build for my PC, wondering if 3mm thick acrylic would be enough for strength?

Sentinel3.14 1 Build 1 point 18 months ago

This is great! It's like a smart version of mine.. : ( I think we are the same age and built around the same time. Your beauteous project is quite similar to mine but I am super jelly of your custom cables. I love the elegance and simplicity of Monolith.

colinreay submitter 3 Builds 1 point 18 months ago

Your build is truly amazing! The design both inside and out is incredible, and I'm honored that you like mine as well! I'll need to PM you about using Raspberry Pi's in the future - the remote start + led system in your build is super unique and interesting.

You're right, we are the same age or very similar - turned 16 a couple months ago.

Muhkyle 1 Build 1 point 18 months ago

This looks better than SO many cases out there, way to out-do industrial designers at their own job! I really love the big side vent, and especially the back "squiggle" vent.

LIVE_AMMO 1 point 18 months ago

I am currently looking for a slim case to replace my old laptop with better overheating remedial alternatives. Going through a number of available options...I have to admit, if yours was on the shelf, it would be right up there amongst the primary choices. Just brilliant!!

What would a laser printer for a beginner cost, nothing too large but a work space of A1/A2? CNC having cheaper alternatives, is something I'm currently considering.

Everyone to their own taste - I still can't get over Noctuas excellence but odd choice of colour.

skyrise 1 Build 1 point 13 months ago

Probaby one of the best SFF builds on this site!

So beautiful, simple and clean!

Great job!

arty667 1 point 11 months ago

I would buy that case instantly! It is simplistic and tiny. Everything you could want in a Mini-ITX case. Please take my +1.

Majin_Sam 1 point 3 months ago

Slick APU build

RiseOfAMD 1 point 1 month ago

Cool! All made out of alluminium?

TechBank 1 Build 0 points 18 months ago

I would totally buy this.... Ugh... I thought all the pics were renders before I clicked on them tbh.

Hey! I just measured the distance from the edge of my motherboard to the center of the cpu both in terms of the height and width of the board. I then did a center rectangle from the point where the two lines (horizontal and vertical) intersected, which is also the center of the CPU!
