I'm leaning towards building a Konami sidescrolling cabinet, like the ones used in The Simpsons, TMNT, etc. I will be using a 25" television, because I will be playing console games as well. The TV will be sitting on a more or less 45 degree angle, which of course brings up the issue of gravity. What is the best (and cheapest) way to fasten it down so that it doesn't slide. I will be leaving it in the case and just using a monitor shelf. Any suggestions?
