The "APU" series appears similar at a glance - and they do offer a case (not rackmount, sadly - although 3rd parties might) to suit. http://www.pcengines.ch/apu.htm At the lower end, the "ALIX" boards are available in a standard 100mm x 160mm "eurocard" format which makes them very easy to rack up.. https://www.dropbox.com/s/81p75pyz1ngsvm6/DSCN0916.JPG?dl=0 Whichever way you do it, a small low-power box running entirely from flash or ssd is likely to be a good "fit and forget" (security updates aside!) solution. If you want to run from a cheap flash card, and are a linux shop, http://linux.voyage.hk/ is a debian-derived system targetting the PCEngines boards which runs with a read-only filesystem. d.
