Ok I have put up a stock of black U-ITX cases. If anyone wants a white one please DM me.

N-ATX will also be in stock soon, sometime next week.

Here is a thread with U-ITX+RTX 5090 FE...
It seems working well (RTX 5090 FE undervolted at around 500W) and reasonible noise (<50% fan speed).
Basically pasthrough GPU are the best GPU type for the U-ITX.

Which cpu cooler is that one? guess you get a better cooling than thermalright axp90-x47 cooper, but is that cooper or granite or just a non as good those metals? which cpu fan would you use? how many mm in total? wonder if it will fit my asus b650e-i.

If you want to get red of those cables it might help to order a cable for rtx4000 as I did on cablemod. quite expensive tough.(50-60eur? cant remember) for one cable that is 2 x PCI (corsair) to the 12pin (12? cant remember) so you dont need to those extra big size adaptors. altough you need to have 3cm straight from the gpu. on mine is hard to see but I got it hardly.

EDIT: I just saw, your gpu conmector is oblicuous , so the 3cm straigh might be not possible or if so, just after needs to turn in a high angle which maybe is not recommended.

In fact it is not my personal U-ITX setup, just the first example with a RTX 5090, double passthrough fans, that seems effective within the U-ITX

The CPU cooler is the Alpenfohn Black Ridge (designed by DanCase). Originally it was only compatible with AM4, not AM5 (except by removing AM5 socket). As far as I understood we can tweak by updating AM5 backplate from Thermal Grizzly (https://www.thermal-grizzly.com/en/backplates/s-tg-bp). However you can get full cooling potential with 120mm fan, pretty hard with VLP RAM. More details in this video.

Regarding the RTX 5090 FE connector, it is well oriented (angled) but the connector remains straight.

The true issue of this build is related to rarity of the RTX 5080/5090 FE models, hands down the best SFF GPU as they are orienting exhausted air...pretty scandalous
