I kind of already know the answer, but would an Intel NUC or similar with around 32 GB of ram be enough for a Proxmox? For my labs I would like to be able to run at least 4 or 5 VMs at once and think 32 GB of RAM is enough with 1 TB internal nvme and an external harddrive, but in the past never had enough RAM or storage.
This will also be my next addition to my current server for a while.
I think my smallest nuc, when I was running proxmox, had 24 gigs with four cores and I was able to get ~4 ubuntu servers running at the same time. Or like 1 Windows 2012 R2 and a couple ubuntu servers. YMMV definitely and worthwhile tuning/building an image that is stripped down
