My place of work was throwing away a stack of 2006 Mac Minis (the exact explanation was "these have been sitting around and we don't know what they are"). I asked if I could take a couple and they said 'sure'. The ones I picked up were the "best" model from late 2006, with a 1.83GHz Core Duo, 2GB RAM and an 80GB hard drive. I have an i5 mini that I use as a Plex server/NAS, but I'd been thinking about moving it upstairs and using it as an HTPC and for light duty gaming for the kids. The Core Duo meets the requirements to take over my Plex setup and I think that's what I'll use one of them for. Any ideas on an inventive use for the other? I was thinking about putting it on Einstein@Home or another distributed computing setup, but I'm not sure if its paltry processing power will have much to contribute. Any other thoughts?
