Last year I got a fanless box from Atlast to use as a headless Linux server running Plex Media Server. Really excellent little box. Quad-core i5, 120GB SSD, 8GB RAM, Ubuntu preinstalled. $600 plus $50 shipping to the US (they're in the UK): http://www.atlastsolutions.com/fanless-mini-itx http://www.atlastsolutions.com/fanless-mini-itx They Atlast guys are also very friendly, and they know Linux.
