Adding a frontend server: requirements

Hello! I have recently discovered this initiative, and I am very keen on trying to support it. I have at my disposal a Lenovo x3650 server with a stable internet connection and an excess of RAM (yeah, I know, quite impressive given the current situation). I am also located in an area where fronted servers are not available, and I wondered what type of system requirements you require your collaborators to provide in case they want to help you further expand coverage. I am posting this on the forum so that other avid collaborators can also see what the requirements are.

Thanking you in advance, I hope the heat wave does not affect you that much.
