Thank you. It will be for testing things I do to the server and proxmox itself. Like messing with ports, firewalls, gpu pass-through testing too (have LXC working but couldnt get KVM to work with a second different gpu), mail systems and new programs and vm services.
I have this set up already: [Build Log] Home lab in a box (first time trying)-x470d4u Proxmox - #10 by HaaStyleCat
The diffrences would be ryzen 2700 vs ryzen 3700x, same mother board (vs b550 thats in the second system I have now that dosent like proxmox), ECC Kingston ram vs 3600 Ripjaws ram, and 1650 Super vs 1660Ti I have in the second system. I would not have the exact dive setup (as I have five 6TB Ironwolfs is raid 10 with a hot spare in the 24/7 system already), but I wouldn’t need that for testing.
The advantages I see to having the same hardware is that I can migrate ISO’s from one system to the other AND/OR follow the exact same procedures when I find what works on the second system in the first system and not run into any hardware issues. That was my thinking but I dont know if that would make much diffrence.
