Log SFFTIME U-ITX : 7 Liters to tame the R7 9800X3D and the RTX 4080 FE!

Just ones with threads yeah

Yep threads are a bit weaker than on the N-ATX and that is why new batches have these panels made out of steel so there shouldn't be any issues. Although I never had such issues with multiple disassembles tbh but maybe you are just a bit more heavy handed than me

Wonderful! For thread, steel is so much more resilient than aluminium! And aluminium is better for panel.. Curiously it is the same combo as the Cerberus-X..

Do you consider using helicoil? This should prevent stripped threads & would still allow you to use aluminum panels, which is lighter.

I have also considered PEM inserts, but they are labor intensive and I didn't want to bump up the price of the case for no tangible gain. Steel panels are the easiest solution and the case is still light enough for shipping

SFFTIME U-ITX : Is it Fixed ? (21th June 2025)

-------------------------------------------------------------------------------------------------------------------------------


Thanks to flawless support from @riba2233 I fixed all the panels with broken threads!

Newer panels are made in steel and the improvement of robustness is immediate to feel and very much welcome! Thanks for this upgrade @riba2233 !

During the GPU assembly process I fumbled on the 2 pins power cable. I should have kept unplugged till the GPU was not secured. Anyway I’ll have time to fix it.

Indeed my BD790i seems damaged and it keeps rebooting while there is a 2-3min GPU load. It could also happen during idle load. It appeared when I tested my RTX 5090 FE inside the FormD T1. I tried many things, switching PSU, checking all the connectors, reverting some Nvidia Drivers…still the same behaviour, like overheating.

That’s already my 3rd dead mini ITX MB…pretty fragile form factor..

Thus here is the U-ITX dominating my almighty Cerberus-X!

Of course, it is only an AU REVOIR not a definitive farewell..

SFFTIME U-ITX : a new try with RTX 5090 FE (26th December 2025)

-------------------------------------------------------------------------------------------------------------------------------

Despite not having fixed, yet, the power button, I decided to test my U-ITX again with the BD790i + RTX 5090 FE + SF1000 combo.

Without further spoiler, I failed at the final stage, mostly due to the cable management. I already saw it was a tight fit with other similar build between the SF1000 and the RTX 5090 FE due to the orientation of the power plug on the GPU.

The second issue was the power extension cable is bumping inside the RTX 5090 FE..not critical, but still an issue.

Thus a conclusion, to make this build, it is required to have custom cables..
