Do you maintain an open source project and need some server hardware for your self-hosted CI or build system? I have two Dell R630 1U dual socket 8-SFF machines and four dual socket Supermicro nodes that fit together in a 24 SFF 2U enclosure. Free to a good home or datacenter, but local pickup in Amsterdam only.
