Small businesses, government and educational institutions, and corporate entities alike can benefit from the reliability and near-silent operation of a fanless Mini-ITX Network Gateway featuring the Untangle software platform. Enclosed in the sturdy, compact, fanless ML250 chassis, the NG100F is durable and "designed to be redesigned" which makes it easy to customize; it's also available with the ML251 chassis, which features a built in LCD display with multifunction controls for headless nodes. The fanless chassis enables users to take advantage of increased reliability that comes from having a dust-proof, solid state solution, as well as providing a silent system free of fan noise.
