Posting in "general" rather than "requests" because this is a market query rather than something I want to do immediately. Maybe pretty soon though, if there's good hosting possibilities.
I'm potentially interested in colo'ing a small server like this one which resembles a souped up Raspberry Pi 3 with a laptop hard drive. It's the size of a paperback book with max power draw about 20 watts according to the graph in the tech spec tab.
Network: 5TB of transfer is sufficient. Gbit port is desirable but 100mbit is ok. 1x ipv4 is desirable but can live with ipv6-only.
Location: US, west coast.
Budget: is $25 realistic?
