Hey,
The only plug-in I am aware of for Motherboard Monitor with Media Center is via VFD support with the VL System's VFD and VFD management software, which supports Motherboard Monitor...

Examples of it's settings can be seen here...

The only other plug-in I am aware of supporting Motherboard Monitor is the My Status plug-in... but that is for MediaPortal.
If you find anything else, let us know... I must admit though - I am no longer using Motherboard Monitor as development has stopped some time ago... have switched to SpeedFan (

What are you actually looking for in a plug-in? I personally would rather see this sort of information on a VFD - rather than have to go to a program in MCE...
frenzz.
