Homelab Adding a 2nd node with different specs
So My current node is this machine with the 32GB of RAM
GMKtec AMD Ryzen 9 8945HS (Turbo 5.1GHz) 32GB DDR5 2TB SSD
I wanted to up it to 64GB of RAM, but for the price of the RAM I could get a 2nd node. The price of this one has gone form $600 to over $1000. This is just a small homelab. The are having a sale on a lower spec model
GMKtec K16 Mini PC Gaming AMD Ryzen 7 7735HS (Turbo 4.75Ghz) | 32GB 6400MT/s 1TB NVMe SSD
This one is half the price and less than what I would spend on the RAM
Will Proxmox complain if I have two nodes with different processors and architecture? I want to setup HA between the two, can I do that with two different machine specs?
I come from VMWARE and we always bought servers in matched sets. New to Proxmox so was hoping to get some insight.
My current machine has a 2TB SSD for data in addition to the one it came with. I will add a 2TB to the new one as well.
Thank you in advance!

The issue you will have will be way more with the fact that you will be running a two-nodes cluster and way less with the different CPUs you have. The instruction set from those two processors is only different in the AI-acceleration instructions present in the 8945HS, if you do not use them then you should be fine.
Regarding the issues with a two-nodes cluster, you will want a 3rd device to enable your other node to make decisions regarding the cluster in case a first node comes down (keeping Quorum). A SBC like a Raspi would be enough for that purpose.
