I have the C1, and I used to use it as a wordpress server and NAS, I bought it as an upgrade to the pi3, but it was not stable, and i replaced it with a pi4. I would like to get a H1 ultra as an aio homelab solution. Proxmox running pfsense, pihole, owncloud, wordpress and whatever else i fancy playing with. It has the 2 2.5gb ethernet ports, perfect for being a DHCP server and firewall (and more), 4 sata ports for a few HDDs to keep all the owncloud data I want to have accessible while away from home, and plenty of ram and cpu power to keep my website snappy, and responsive, which is the biggest complaint I have from my wife, who spend s her time uploading photos for the family. My wordpress is currently hosted on a oracle free tier instance, with sshfs access to my Nas, but i want to bring it back in house.
The H1 seems a great idea, even if it is x86, but it’s a perfect fit for your needs.
I’m not an arm snob, or raspberry pi fanboy, I’ll go with whatever works, AMD by preference though.
