Not much to say about this one, really. See the pictures. If you can't, I don't think describing the mod would be of any use.
The display isn't really useful. I just wanted to have a small LCD in there. So I made it display for how long the NES has been on. Any other ideas?
Please don't try to analyse the board. I can't play chess. But the Chessmaster cartridge looks good through the window I cut in the top of the NES. Maybe I'll make another post with a picture from the top.
The texture of the "stone" spray paint is really rough. Maybe if the plastic was colder than the air around it it could almost fool somebody into believing it's some kind of stone at first.
Now I just need games to play on it. I finally gave back a rented game after 20 years of forgetting it, now I only have The Chessmaster, which I don't care for very much and Super Mario Bros. 3 - my favourite - which started to have an unbearable graphical glitch a day after I finished the NES case mod. (Yes, it's the cartridge that's damaged, not the console.)
