Summary:
This motherboard was salvaged from an XMG NEO E22. I didn't want the hardware to go to waste and decided to learn CAD with Fusion360 along with my P1S. It took a little over 2 months to wrap my head around Fusion and the different tricks to get somewhat prototype results.

This isn't the final chassis as I will be printing in an engineering filament at a later date. For now, it is a mixture of Matte PETG and PETG-CF.

Important details:
Laptops can be a little tricky to convert to a SFFPC, this is due to the MUX switching and how external ports are configured. To avoid issues, I wired in an EDP cable from the motherboard to a 40P EDP converter board, this offers a HDMI signal which is next to one of the exhaust vents. The brilliant thing about this addition is that I have BIOS & Windows access that is seamless.

Hardware & Temperatures:

As you can imagine, with the chassis getting plenty of airflow, there is no issues with internal temperatures. With a highly configurable BIOS and control centre software, I have tuned in a -30mv CPU offset, along with a 10c TJ Max offset.

I also achieve maximum GPU performance with a temperature limit of 80c, the results in very low fan noise and all available performance.

To create a solid chassis, I used threaded inserts and a dedicated motherboard tray that is centre to the chassis. Everything is mounted with either M2 or M3 hex hardware.

Overall, I am incredibly pleased with the result and I now have something unique.

I wasn't browsing LTT expecting to get turned on like this

Sick build. I love the upcycling, I love the design, I love the outcome.

9/10

10/10 when you get it properly printed.

Neat! Don't think there's a point to reprint in more fancy filaments though, PETG should be fine for anything PC-related. If the case is reaching PETG glass transition temps there's something wrong with the cooling anyway.

Some QOL changes.

Opted for printed heatsink fan covers instead of the traditional tape/mylar.
M.2 heatsink with centre pad cut away, allows both DDR5 SPD's to be cooled effectively.
EDP to HDMI converter board for HDMI spoof - debug display if required. No longer encounters ACPI BSOD during boot sequence due to missing internal display.
