Like 1GB RAM or less. Enough storage to run a web server for a static website and a few gigs for file hosting, possibly.
Obviously will accept greater if they are cheap. I'm just putting this amount because I doubt I'll be running anything too serious.
pretty sure they have stuff like that, they aren't building server farms for people. They also have great customer service and again, they keep things anonymous and are privacy advocates
