I remember seeing this compact server device from Terra Soft Solutions years ago and thinking they were cool, but could never afford one. I thought it would be interesting now to try to track one down to play around with, but it seems that they are very rare and hard to find, so I'm having no luck at all at this point. I know their typical usage was probably CPU clusters in government, education, research, etc. fields, so maybe looking on places like eBay is the wrong way to go about it. Any one have any idea where I could track down one or a few of these things?
