Hey guys!
I just bought a second hand HP Z400 for almost nothing a few days ago, trying to put a huge VM of kali in there, use it as a NAS and those general home server things. First, I used an HDD I had lying around (old 120GB Laptop HDD), which worked fine, but my VM is 80GB in .raw format. I buy a brand new 2TB HDD, mount it through the web console according to a YT video, all good. I SCP / winSCP the file to my server, and that went fine. 12 hours later (this evening) I turn on my PC and Z400, only to hear electric noise coming from time to time from the PSU. After some intense troubleshooting, I discover that running a live non-ram linux version does not have this effect, even mounting the HDD and giving it some time. A while later, I discover that even running the setup (during the first leg of the installation was the first instance) the PSU puts out some arcing noises. I tried different configurations (putting in only one HDD, both of them and reinstalling), ultimately all those lead to the same outcome - PSU buzzing during runtime.
This is exactly the source where I got it:

TL; DR - PSU buzzes with proxmox, but not with other OSes, seems like. There is still some potential troubleshooting to be done, sure, but until then, awaiting your ideas
