Weird, I've already got the 3/4" birch plywood in the garage for building mine. I've built about everything in my office out of birch or red oak plywood, and use band-it edging to finish it off. For the pedestal stand, I'm thinking black T-mold though, the band-it edge looks good, but it's time consuming. I use low gloss tongue oil (really wiping varnish) or semi gloss polyurethane for my finishes. I've nearly moved completely away from poly, it's just such a bitch with to deal with, all the way down to the clean up, where as tongue oil is wipe on, wipe off. After tons of measurements and considerations, I'm aiming for a control panel height at the top front base, of 38". This drops my star wars yoke 1 1/2 inches below the arcade height, but I think that will still be fine. I'm just over 5' 10", and have tested this on cardboard boxes to no end to see if it feels right. I finally came to the your conclusion, feels good standing up, and should be okay on a stool too. Anyone else reading this, don't go there! I purchased a sheet of mdf for the bottom plate, but man, just look at that stuff wrong and it chips. I've always hated mdf, and that was the last straw for me.
