Dual rad, dual orientation T1 build with no compromise fans
TL;DR 9800X3D + RTX5080 watercooled in a T1 using LOBO and Alphacool 1-slot waterblocks, 240+280 thin rads (TX240, HPE20) cooled by Noctua NFA-12 G1s and Toughfan 14 Pros.
As for many, the original inspiration came from Optimum, but also the crazy builds you guys post here on Reddit. I have planned this ever since alphacool announced their 1slot reference RTX 5080 block. I believed I could make a full thickness fans fit on the motherboard side rad when mounting the PSU not-so-traditionally on the GPU side in 90 degree rotation. I wanted the side rad fans to double as airflow for the motherboard. Ultimately the result is a T1 build with 140x27mm side rad fans, and afaik its a first. If you know about such build or have one, please let me know :).
I am bad at making things nice, so I concentrate on the functional side. No hard tubes, no tubes crossing ram in a fixed way.. I am going to design a front panel to allow PSU heat exhaust and ability to stand on the front.. the glued on front feet are super janky... but I worked 3 months on this, with my Fusion360 being offline. Soft tubes allow opening the rads for both access and better breathing (tested under pressure that the dynamic stress does not introduce leaks). Everything can be accessed and removed except the GPU, that would require QDCs for which there is zero space. 1slot GPU config required a custom QDC assembly, which I mainly wanted for filling but also future chilling experiments.

Not thanks to Thermalright for specifying the Toughfans as 25mm. Not even close :)
