Could someone tell me what the hardware requirements are to run the server? I've not found any online.

Fleet itself is fairly lightweight and the only hard requirement is 4GB of RAM for vulnerability processing. The reference architecture is a good resource for figuring out how to dial in resources for your need: https://fleetdm.com/docs/deploy/reference-architectures#a-href-https-calculator-aws-estimate-id-f-3-da-0597-a-172-c-6-a-0-a-3683023-e-2700-a-6-df-6-d-42-c-0-b-up-to-300000-hosts-a

I'm sorry. I found those, but those are for cloud deployments. Are there none specific for home deployments? I can't reference the different terminologies used by cloud providers unfortunately 😕

How many hosts are you planning on enrolling in Fleet?

I understand, I got some assistance from a friend and I've set it up already. Although I ran in to some other issue, I forgot that I had a self-signed certificate when enrolling a host, and so I didn't use the --fleet-certificate option and installed it. Now when i do use the option to generate a new installation file I get this error:
