I found a store selling real cheap N64's so I bought one and figured I'd customize the case a bit. After a little thought, I decided to go with the Legend of Zelda theme. My thought behind the design was that if there was an ancient Triforce pedestal found in Kokiri forest, this is what it would look like. As such, I went with the that.
The base was painted gunmetal, I figured, whoever made the 'pedestal' would have made it out of metal to last. Next, the top was painted brown to look like aged wood ( possibly donated courteously by the Great Deku Tree). As it was put together, the carpenter cut out the symbol of the of the Triforce into the wood and put glass in the etchings, maybe to let some curious traveler look into the mystery's the pedestal might hold inside. However, I wanted it to look old, so the glass is cracked in places, and as you can see, the wood has a little moss growing on it (but not too much to get annoying and to get messy when you move the system.)
Finally, the 'On' red LED light was replaced with a more appropriate green light to go with the Zelda theme.
