Yes, this was definetely a side quest, but postmarketOS indeed is a real Linux distribution that is perfectly usable! I just want to experiment with this tablet, and with U-Boot providing an EFI environment now adapted, I (or anyone) should be able to boot any distribution (Arch Linux ARM, Debian, etc). Ubuntu was just my personal choice here :)

In your case, it seems you had an automated (semi-automated, maybe?) feedback loop. In my case, I was the feedback loop :D which ended up being the bottleneck for some parts...

The E5 2620-v4 only supports DDR4.

Certainly! The original [link](https://makerworld.com/en/models/488435-12-trays-hdd-enclosu...) already has information. On the back I mounted SATA connectors (SATA-to-SATA, with power). I have a 1U PSU in the enclosure, which has SATA-power cables connected to the back connectors. Then, I have two SAS to 8 SATA cable that connects to the HBA card in my server on the Mini-SAS end and to the SATA connectors on the back on the enclosure. I hope that makes sense :)

Yes, I would have loved to use a 'better' material, but my printer is not enclosed and I'm not sure it can print CF filaments (I think I would need to change the hot end at least). But soon I will hopefully get my hands on a new BambuLab printer which should let me play with those materials!

Thanks for noticing that! I'll try to fix right away (of course it is not happening on my local dev environment...)

Fortunately, the R740 is around 230W, and the switches, routers, and everything around seems to only take 40W. Which means I'm below 300W, and I guess we have cheaper electricity in France as I don't pay as much as you (I think less than 50€/month for the homelab)

I used PETG to print it, which should support the heat without problems. I also added two fans behind, so that the disks and enclosure stays cold. For now, I only have 4 drives in it, and it does not move at all and holds perfectly fine.
