Supermicro X10 generation barebones systems trade brand polish for practicality. IPMI is included with no license tier, the fans are generally quieter than Dell or HP equivalents, and the boards use standard connectors so replacement parts are easy. Popular with people who want a server that does not sound like a vacuum cleaner.
