I have a Dell R730XD with 128Gb RAM and a 49TB array. It’s way overkill for my needs, but I have fun with a lot of docker containers running on Unraid. I can also host a few web apps for my own needs. The Unraid docker GUI became way too slow to use, so now I manage everything through Portainer and modified everything to use stacks and docker compose. It’s much easier to manage now.
All will depend on the pricing. But it will be hard to go against the big three.
