Interesting Reschke. I've been thinking of doing the exact same thing for a few weeks, but I haven't decided if I want to put the PC inside the base or inside the console. I am gonna put it outa the way though, I know that.
You might consider using a late model firebird/trans am seat, the reason I say that is they also have an up/down adjustment in the front of the seat which would let you adjust for comfort with your pedals.
