They don't.Not sure if the drives remain powered if the rear switch is on, but the system is off. Something for me to go check on my lab box, I guess.

Sounds like a nice build. Are you still using the original case, and how did you mount the GPU?attaching a GPU with a riser cable
Ah, this was only temporary. Doesn't appear that Proxmox can easily install over a serial console alone, so I went this route rather than deal with installing on another machine and swapping the disk over. Now that it's installed, I'm back to using the serial console alone, since—absent decent IPMI—that's easier for me to deal with than a keyboard and monitor would be.Sounds like a nice build.

Thanks for the background.this was only temporary.
Not sure why I didn't think of this before. I reversed the fans and it's so much better with the air duct guide.Alright, instead of adding another fan, I decided to model and 3d print an air duct. Here's the file should anyone want to try. The attached model is a revision of the one in the photos. This takes the shunt resistor (I think) into account and additional vent holes for better airflow. Print using a 0.4mm nozzle at 0.2mm layer height. I recommend PETG since that heatsink will get hot enough to melt PLA.
It's currently idling at 43c (old version) 36c - 39c (new version) in an office that's at 26.7c (80F) ambient temperature. The fan is a little quieter now as well.
Realistically, after 8 hours of idling, it's around 44c. Earlier numbers were too optimistic. Still not bad but not WOW as I was hoping for.

You could also install it over Debian as well Install Proxmox VE on Debian 11 Bullseye - Proxmox VERegarding Proxmox install without a video card...
You can do it if you have a hypervisor that allows USB drives to connect to VMs. The basic concept is to install Proxmox as a VM using a USB attached SATA drive, then modifying Proxmox to use a serial port for console going forward. You can do the same with a PC and a SATA drive, just skip the VM bits, install, and edit Proxmox files to use the serial port.
My chicken scratch notes (obviously I am not a tech doc writer for a living LOL)...
VMware Fusion (should work just fine with VMware Workstation too)
-Make a new VM using Proxmox ISO
-UEFI, Debian 10x 64bit,
Adjust VM Settings and Resources:
-Network Adapter -> Bridged Networking
-Enable all CPU advanced functions
-Hard Disk -> Advanced options -> Remove Disk
-Power On to Firmware
-VMware Menu: USB & Bluetooth -> Connect USB drive
-VM Firmware Menu -> Reset the system
-Should boot from the ISO, install Proxmox as normal, and reboot

Move SATA drive to the CX-570/770 box and it should boot, and display console via the serial port.
True and it usually works fine. But over the years I have seen less-than-enthusiastic support for such installs in the Proxmox forums, so I tend to prefer native installs. YMMV of course.You could also install it over Debian as well Install Proxmox VE on Debian 11 Bullseye - Proxmox VE
Debian can be installed over serial at the Grub boot by pressing 'e' at the install option. I recommend selecting the expert install option under advanced. Then in the edit screen, look for the line that has 'vga=788 ---' (should be the middle line). You'll want to edit it to say 'vga=off --- console=ttyS0,115200n8' and then press ctrl+x to boot with those parameters. Then quickly reconnect with Putty with the 115200 baud rate. In older versions of Debian, you would have to edit the grub config to default to console but this seems to be correctly set after installation on Debian 11. Once that's done you can follow the guide above to install proxmox.
Gotcha! It has been a while since I've installed proxmox. I didn't realize they don't provide much support for that method.True and it usually works fine. But over the years I have seen less-than-enthusiastic support for such installs in the Proxmox forums, so I tend to prefer native installs. YMMV of course.
I also should have mentioned my notes for headless install was for 6.x Proxmox, not sure if they are accurate for 7.x.
ECC and non-ECC unbuffered (udimm) DDR3/DDR3L 1066/1333/1600Hey anyone know what kind of memory these take ?
would you be able to share the extender cable you used for the video card? i'd like to source one from ebay or amazon.Ah, this was only temporary. Doesn't appear that Proxmox can easily install over a serial console alone, so I went this route rather than deal with installing on another machine and swapping the disk over.

This was mentioned previously in the thread, but only E5/E7-series Xeons accept Reg DIMMs. Celeron/Pentium/E3-Xeons will only accept unbuffered DIMMs.i wasn't able to get registered ECC memory working in my CX770, only udimms
