More Ram
Due to Black Week(s), I found a pair of 32GB RAM (64GB in total) for cheap, and bought them. I planned this for months since I failed to buy them twice earlier this year. I have sit on more than 80% of RAM usage for soon 2 years now and really needed them so I could expand my homelab further. Therefore, I now have 128GB or RAM on my Proxmox node, and am very excited.
