I might sum up here from recent additions (replies) on this mailing list regarding current low-power server options (x86/32bit) for XS:
1) FitPC2i - Dual Ethernet, fanless, poss heat-issue (heat sink), PhoenixBIOS (no Wake-on-LAN), 12W draw (poss ~5W idle) http://www.fit-pc.com/web/fit-pc/fit-pc2i-specifications/ 2) SolidLogic - (VIA C7, 25W draw) current sys in use not available for purchase, EU options in links below http://www.logicsupply.eu/systems/intel-atom/ http://www.logicsupply.eu/systems/fanless/ deployment sites: Jamaica 3) MSi WindBox - '10 Atom D510, 4GB DDR2 - ~35W, drawback single Ethernet NIC (USB WiFi adapter) http://fr.msi.com/models/Wind%20Box%20DC500 deployment sites: Nepal, Haiti, Philippines 4) EPC-AT270 - Dual Ethernet (Wake on LAN), fanless, drawback '08 model Atom N270 (2GB DDR2) - http://www.avalue.com.tw/products/EPC-AT270.cfm deployment sites: PNG, Oceania? These solutions generally haven't changed in the last two years, in Q2, 2012 now these are the current stable options for low-power x86? If that's the reality, I assume we can make a decision around these options, taking site specific considerations into account, and plan for possible involvement (replacement) down the line (1-2+ years) with any future server development for ARM/plug/etc and what suitable working model is devised around it.
