I'm about to build a custom rig using a red NZXT Phantom 530 case. It reminds me of an Audi R8 or a similar Audi concept car. It's absolutely gorgeous. When I press my power button, I want my computer to play an audio file so I can hear the sound of a super car turning on. How can this be done? Are there any easy kits out there? I need it to be an independent system so that it will play the moment I hit the power on button. I'm open to any ideas about this. I can think of a number of ways to make it work, but I don't have the expertise needed to tackle this one from scratch.
