You just need to add a set of Guncon 2's and a racing wheel...
I got into the PS2 recently. I have most of the North American releases but the only games I come back to play frequently are the light gun games. The PS2 is easily the best shooting game console and the official Namco guns are easily the best home gun controllers ever made.
Maybe you could put a PS3 in there too. A PS3 would make better use of that awesome fight stick panel...
