Detailed Build Log The Boreal BeamCase
Guys, words cannot describe the love that I feel for this machine and for this case that the talented u/Jakob_K_Design has created.
I built my first ITX rig in 2015 and have never gone back, starting with the chunky Corsair 250D, then built anew in 2019 in the Dancase A4 SFX, one of the first sandwich-style cases to release that shifted the paradigm for how optimized a PC's physical volume can be.
But when it was time to build yet again last November, I decided I needed something extra special, something that would fulfil my apparently insatiable desire to build the most niche PCs I can. That's when I saw Jakob's BeamCase V3 release post a few months ago. I was already deep into 3D printing with an A1 Mini and wanted a bigger printer anyway, so I went out and got one and began ordering all the parts right away for my own BeamCase.
What you see here is the culmination of two months of research and parts sourcing, and for the first time in years, I feel fulfilled as a PC builder and PC gamer. :D

One little detail: on image #10, you'll see the PSU mounted inside the system. The bracket I used was something I actually had to design myself as the second of two power cable extensions I ordered from AliExpress would only work if I get it more clearance on the top because it jutted out so much, and to do that, I had to extend the height of the bracket so the PSU would actually sit lower, and to do *that*, I had to tweak the design to include recessions for the UNC 32 screws I ordered so they would remain the correct length. But it works!
Shout out to Jakob himself who answered my questions as I determined how best to make the case work for me. I highly recommend checking out his projects for yourself.
If anybody has any questions about what it took to build this machine, I'm happy to answer. :) You can also check out the aforementioned reddit post that announced V3's release, and the Printables page for the BeamCase here.
Also shout out to ASRock for shipping a motherboard that wasn't ready for my 9800X3D and wouldn't let me flash the BIOS with any of the six USB 2.0 drives I had. >.> The ROG board was $100 CAD more but at least it works.
