Utilite Pro is a quad core ARM cortex-A9 machine with up to 4 GB of RAM, up to 512 GB mSATA SSD, HDMI and DVI-D output, dual (2x) 1GB nics, a built in wireless card and 4 USB ports. The guys from OffSec show you how to build your Arm image to run on it. Not too bad for a $200 dropbox that you can use on site during pentests.
