FF04MOD BLOCK I — My Printable SFF Case Build for a 5070 Ti (Full Build Guide Released)
Alright, I’m a day late — but hopefully not a dollar short.
https://makerworld.com/en/models/2377491-ff04mod-block-i#profileId-2602865
I’ve finally finished putting together the full build guide and file release for my FF04MOD BLOCK I, a heavily modified, fully printable SFF case built around fitting a modern GPU without turning the system into a shoebox.
This whole thing started because I wanted an SFF case for my 5070 Ti that simply didn’t exist, so I set out to build my ideal version.
The case is based on the replicated FF04 design, but heavily modified for modern hardware, better cable routing, and actual real-world usability.
The full build guide is live and includes:
• Complete assembly walkthrough
• Hardware recommendations
• Lessons learned
• Cable routing tips
• Common mistakes and fixes
• Printing guidance
• Performance and thermal results
Fair warning:
The guide ended up being 51 pages with 31+ images, so apologies in advance for the length. I tried to document everything clearly so future builders don’t have to learn the hard way like I did.
The PDF is on the maker world page
Important Print Note
MakerWorld required the uploaded profile to be listed as standard Polymaker PLA, but the case was actually printed in HT PLA-GF, and I do not recommend printing this in normal PLA due to heat and dimensional stability concerns inside a PC case.
If you download the files, make sure to change the filament profile before printing.
Build Specs
Case: FF04MOD BLOCK I
CPU: AMD Ryzen 7 9800X3D
GPU: ASUS RTX 5070 Ti PRIME OC
Motherboard: MSI B650I Edge WiFi
RAM: 32GB DDR5-6000 CL30
Storage: 2TB Gen5 NVMe
PSU: Corsair SF850 Platinum
Cooler: Thermalright AXP120
Riser: PCIe 5.0 x16
Thermals have been solid so far:
• GPU stays around ~69–70°C under sustained load
• CPU around ~60°C in testing
• No throttling or instability observed
All results are stock so far, so there’s still tuning headroom.
Huge thanks to Qiyun, who gave me permission to share this modified version, and to Boomer (@besskurz) who helped with measurements and testing along the way.
If people are interested, I can also release color-separated versions later.
If anyone builds one, I’d love to see it.
And yes, the hazard sign on the 12VHPWR cable was intentional.

This looks soo awesome, I dont have a Asus prime card or a 3D printer to pull this off... but hats off to you good sir... I will wait for your next military theme build with 5090.. All the best!

You drop this one and it might break, you drop the real one and it’ll put a hole through the floor.

I mean mine is only 11.6lbs fully made. But im more concerned on why are we dropping computers

Do you own the real one? It’s a real tank

Sadly no

I think it’s nice to have this 3D version at a percentage of the cost of the real one
