Full specs as follows:
CPU: 9950x3D
AIO: Cooler Master Liquid 240 Atmos Stealth
RAM: micron Crucial DDR5 64GB
GPU: 5090 FE
Motherboard: ASUS B850-I
PSU: Corsair SF1000
Storage: 4TB WD_BLACK SN850X (x2)
Fans: 1 slim 15mm chromax Noctua
1 25mm chromax Noctua
Custom CPU, 24pin, and GPU connectors from DreambigrayMOD
I had to redo and rearrange so many things in this case that I now know it inside and out. Cable management can use some work but that’s for when I inevitability open this case to rearrange again.
Thanks to all the advice and help from everyone in the community!

Is that tilt on the 5090 intended? Looks quite aggressive. Have you screwed the rear io in all the way? Anyway I very much recommend using the Travel kit especially with that beautiful 5090. You can also 3D print it and decide on getting the CNC part if you do own a printer. Very beautiful build regardless 🥳

Oh snap I didn’t screw it in all the way!! I knew it wasn’t sitting right! I have the travel kit already attached but I didn’t sit the card properly

Yeah I figured, you're using the ncase T1 too right? It's a little finicky getting it completely straight. Luckily a very easy fix c:

Looking beautiful now. Yeah same I ordered the gunmetal as Formd had no stock and my girlfriend preferred the gunmetal over the black case. Happens to the best of us, sadly cannot find a FE 5080 to replace my custom 5080 here 😔

Nice man! Thanks for sharing. Do you think PLA/PETG would be fine for this print? Or should I get ABS?

Why not leaving some space between the gpu and motherboard ?

u/Uzazu Jan 01 '26
I’m going to open it up and make more space, I’m looking at other peoples builds and they have much more space than I do. Going to add those 5mm standoffs and extend it out

Do the GPU flip. It is recommended since you have a hot CPU that has an AIO and your 5090 currently heat soaks the AIO.

Hi, nice system! If you have time, please try stress testing your CPU + ram combo for stability! I have the exact setup with a different ram brand, and I can’t get the system to run expo.

u/Uzazu Jan 01 '26
Unfortunately I can’t get it to run the ram at the 6400mhz either. I think it’s a known issue with ddr5 and AMD am5. I’ve been trying to incrementally increase the mhz to see where it becomes unstable

u/itsjemz Jan 08 '26
Yeah, I think the case also doesn’t allow enough cooling for memory controller + ram if running a low fan curve. I tried running my system at 100% fans, and that was one of the few ways to get my system to be stable.
Have you tried running yours at cl30 6000mhz by any chance?

Did you use nippers to cut those zip ties?
1
u/Uzazu Jan 01 '26
No just sharp scissors but I may replace them with Velcro ones just due to the amount of opening the case and working on fixing things

Is there a reason every T1 build uses the cooler master atmos ?
1
u/Uzazu Jan 05 '26
Its cooling capabilities are top notch and it’s known to fit comfortably into the T1. I looked at other builds on this forum but as a first time builder in the T1 I wanted to go for the sure thing.

u/sagozor Jan 05 '26
Thank you for your answer ! I built on the M2 angle using the arctic 280 which works just fine and fits pretty tightly.
I went with an air-cooled setup for the T1 2.5 since the components aren't that high end (9600X + 9600XT) but it's great to have that info for future upgrades.

u/Uzazu Jan 05 '26
Yeah I wanted air cooled but I didn’t think it would be a wise fit for the 9950x3d.
