for a home automation project I'm search for a small and cheap computer which is capable of running a small webservice. It should have the following features:
- Linux enabled (Debian, OpenWRT, ...)
- small form factor (ca. 4"x4" resp. 10cm x 10cm or below)
- chassis
- fanless
- low power (<5W)
- USB port(s)
- ethernet port
- opt. WiFi
- opt. Z-Wave or ZigBee
- min. 128MB RAM
- min. 256MB non volatile storage (NAND Flash, SD Card slot, ...)
- internal or external power supply
- available in EU, <100 EUR
There are plenty projects which need a small Linux box thus hopefully somebody has already found and used such an embedded computer.
