Migrated my last power-sucking machine (a Mac Pro 2006), that acted as a media server, to a 2012 Mac Mini, and decommissioned her. My 2013 Mac Pro (not considered early Intel, but eh...) has already been decommissioned, and it's files moved to an M2 Mac Mini. Running an all-Mini "shop" here now- 2009 for development (I'll post pics of this monstrosity in the near future), 2011 for media streaming, 2012 for media serving, M2 for daily use...
... and a problematic 2005 G4 that I *will* get running again, dammit...
