Not exacty enterprise grade servers then?

Supermicro sells Atom-based SKUs with enterprise features like a BMC+IPMI, 10Gb SFP+ ports, ECC memory, SFF-8087 ports, chassis intrusion detection, etc.

And do you need a full-on enterprise-grade server? Given the choice between a 1U server whose fans even at minimal utilisation can still be heard three doors away and something with a low-power/laptop-grade CPU that does the same job silently and with little power use, I'll take the latter.
