I'm about to put my MGCD on eBay and figured I'd see if anyone here wants it before I have to pay fee's to sell it.
The MGCD for those that dont know is a conversion board set and has modifications that can be set such as requirein token/coin to play a game, set the game up to limit play per credit etc. The MGCD completely JAMMA-izes a dreamcase (controls, video, audio). It's as simple as plugging in the JAMMA harness and setting dipswitches if special modes like the ones listed above are desired.
The MGCD comes in a self contained box with a strap inside of the box for concealing / mounting the dreamcast inside with the MGCD. The dip switches are mounted on the outside of the housing should you wish to turn off a special feature without needing to open up the enclosure.
Here are some pics to give you an idea of what it looks like:

and inside

I will include a dreamcast to go inside it and possibly a game or two (I will have to see what games I want to part with).
Thanks for looking.
