Looks good! That is a lot of buttons though, are you going to be playing a lot of SF4?? I don't think SF4 has a 4 player co-op mode, you might be making more work for yourself than necessary. If you really want to pimp it though I would add 26 inch spinners and some neon! Joking...Don't pimp it too much or it might looks cheesy. Maybe some Electric Ice buttons and an LED Wiz?
