If you haven’t played Enderal it’s worth a playthrough. It’s a free total conversion mod of Skyrim.

I’m using a commercial desktop with an i5 Sandy bridge. I maxed out to 32Gb of ram only because I’m running trueNAS, debian with containers, and home assistant. Most RAM goes to trueNAS and trueNAS doesn’t accurately report ram. For CPU, mostly just task limited but I don’t really think thats a proxmox issue. Obviously it’s not going to support an enterprise or even small business but it works for what I need of less than 4 users on my budget.

Proxmox doesn’t really ask for much but I probably would recommend docker for your arm devices.

Should cover any polite web crawlers but it is voluntary.

Might have to put it behind a captcha or other type to severely limit automated access.

It’s not realistic to assume it won’t get scraped eventually. Such as someone paying people to bypass capatcha or web crawlers that don’t respect robots.txt. I also don’t know if Google and Microsoft bundle their AI data collection that doesn’t also remove your site from web search.
