Hello there.
I've spent the last months carefully engineering my dream SFF case: ℂ𝔸𝕊𝔼ℕ𝔻ℝ𝔸
She follows a more restrained design with no RGB, envisioned not to live her life hidden away under a desk, but rather to turn heads and be recognized.


With 160mins heavy gaming (MSFS24, Indiana Jones ATGC, ...) I averaged CPU 58°C (Tdie) and GPU 66°C (Tdie) / 90°C (Tmem). That's with fans set to 35dbA.


So whats left to finish? The single biggest remaining obstacle is that - even though the protoype works perfectly enough in my day to day life - I decided to re-engineer the whole structure to accept up to 55mm CPU coolers (current limit: 47mm), while keeping the overall volume similar. (keyboard in picture is Rapoo E2700 - don't get fooled, it's a tiny one!!)

To create a satisfying physical interaction, CASEDNRA is crafted from recycled acrylic glass combined with beechwood panels. The party trick is that, with the help of clever folding techniques, a single envelope-style shell wraps around a modular structure, revealing the interior when needed.made to (un)fold

hardware support:
- Mobo
- ► mini-ITX
- CPU
- ► cooler up to 55mm
- RAM
- ► height up to 61mm

- ► SFX (idealy with modular cable mngmt.)
- GPU
- ► up to 63x157x327mm
- ► PCIe 4.0x16 or 3.0x1 riser available

CASEDNRA was originally intended as a one off build - Recognizing her unique character, I set the challenge to create a real product, not just a prototype! Endless refinement-pain and developing later and I am almost finished. To boost development and bring CASENDRA to life, a Kickstarter campaign was launched on May 1st.status

To fully circle the sustainability aspect, a tailor-made packaging consisting of nothing but cardboard (and one anti-static bag) has been created.packaging / assembly

No, maximum temperatures of up to 110°C (TJmax) can only be observed in extreme scenarios and only inside of computing components (e.g., CPU temperature) - never on a touching surface! Even if they were, that by far wouldn't be enough: the ignition temperature of beech wood and MDF is only over 200 to 300°C, which is right around where most plastics (like fans) are already melted or heavily heat deformed. Therefore, no fire hazard is to be expected if handled as intended.[FAQ] increased Firehazard?
There is more! Being a modular structure - I pictured CASENDRA as a great choice for a visually appealing NAS/homelab case. Among other upgrades, there is a "Memoria Kit" which enables hybrid setups between drives and PCIe devices in the GPU compartment:one more thing
CASENDRA is smaller than the Terra: at ~21cm (8.27") she's just about as tall as your typical DVD box.size comparison
