I finally got the new keyboard ($30 from buy.com) and mouse ($6 from newegg.com).
They match pefectly anf are actually a lot more comfortable to use than my old standard stuff.

I drilled some holes for buttons to hold the pinball controls, admin buttons and a bigger spinner. It would have been nice to do this a while ago when I built everything else, but there were problems with the drill bit.

The pinball buttons are on the sides of the control panel and are in pairs. One button is for the flipper and the other is for shaking the machine. I was thinking that it would be a great idea if the shake buttons could be mapped to the mouse, so I could give the trackball a whack if I wanted to smack the machine around. It would be fun to actually punch something to move a virtual machine.

The admin buttons are on the top of the machine. The left button is the Esc key to back out of games because it is used to ofter. The right button is the Shazaam button. The Shazaam button is like holding shift or control. With it, you double the number of available buttons. I'm mapping player one's buttons to tab, enter, pause, save game, etc.

As for the spinner, I'm going with the TurboTwist 2. The control panel wood that I bought from Kneival was set up to use a spinner that doesn't have the resolution to play Arkanoid, a definite favorite of mine. I also like that this spinner has a weight and a rubber knob for a sturdier feel.
