Four 1Gbe NICs, passive cooling, with respectable performance from a US-based system integrator with a good reputation and the option for CoreBoot?  What's not to like?  I set mine up as an over-spec'd pfSense firewall to replace some rather underwhelming Asus gear.  Combined with some Unifi APs and managed switching gear, it adds up to a pretty powerful home networking setup!Mine came bundled with a UPS backup power supply that has a Y-cable that enables it to power both the Protectli and my Motorola Cable Modem ;-)
