Thanks everyone! I had a broken Xbox at home, so I took it apart and took all of the guts out (wasn't very hard at all). I bought some acrylic and silicone from lowes, cut and glued the pieces. Then I used a dremmel to cut the viewing window. I then siliconed the tank to the viewing window and put the Xbox casing back together. I added a green led
flashlight from Walmart for now to light it. When you lift the top gray gate off, you have access to your light and can feed and do water changes from there.
