#3Nice write up! For this sort of thing, I have leaned towards AMD Epyc, Intel e810, and DPDK for the software stack. Unfortunately, lately the supermicro H13SSL line of mobo's appear to have become near-unobtainable with ridiculous 6+ month lead times.

#4Wow, 249 CHF for 8x fans is insane. The grip Noctua has on people! Nice workstation.

Why that mobo specifically ?

No idea, you can still get one-off boards here and there, but buying anything in quantity has been tricky. I can only surmise supermicro's resources are largely tied up with AI data center build out, with everything else relegated to short runs.

they aren't cheap, but noctua's latest 120mm fans are arguably as good as it gets, in quantifiable ways: https://www.hwcooling.net/en/noctua-nf-a12x25-g2-pwm-the-kin...

#8It is too bad this important work needed to be done on the cheap. You'd think if the Swiss National Bank was involved, you could get a proper budget....
It would have been a lot easier to focus on the important implementation details if the server was an off the shelf Lenovo datacenter server (SD550?) with a pair of 100 gig/s NVIDIA cards in it.
(Source: last month I set up a machine like this for a colleague to do approximately the same task. I spent "copy and paste the production server config" time on it, not a week.)

Personally was always a fan of just going with the largest fans possible - surprised we don't see more cases designed around 140mm and larger. 200mm is much less common but has a more pleasing noise profile
