EDIT: Oh my goodness, thank you so much to all of the awesome PCPP staff for featuring the build, and all of the awesome community. You guys rock!
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!
