For sure. I managed to snag a "second hand" University NeXT Computer (the 1st gen Cube) for a few bucks on eBay a number of years ago with the Frog Design monitor, and a 68040 upgrade board. Going for almost $3000 now on eBay based on completed listings. The upgrade board alone is $600. I also managed to snag a 2nd gen 128kb Macintosh for $5 at a second hand computer shop.
