This is a little vesa mount stand modified to fit underneath the Spectrum Next computer. It allows a small (12" in my case) monitor panel to sit just above the keyboard of the Next.
Bolt the pieces together with M3 or M4 nuts and bolts and use very short M4 bolts to fasten the mount to the back of the monitor.
The author remixed this model.
Base extended to fit Spectrum Next. Verticals extended to allow monitor to sit over the Next's case.
