UK-based managed service provider SysFix Group offers customers a free small business server-- if they have 3 computers under a SysFix support contract.
Similar to a HaaS service, the offer provides businesses with a free server for internal file sharing complete with IDS, HTTP proxy, traffic priority and an online backup option.
The server will be available for clients for the duration of their IT contracts-- and could also be put under long-term support contracts, akin to HaaS deals.
