18.5"wide, 17"deep, 22"tall.....the control panel is 7" deep
Making this with oak, been working on this off and on for 6 months

I think I crammed too much in the control panel though, has omni-stick, 4 buttons a trackball and a spinner
unfortunately, i'm gonna be pretty busy for the next month so this will have to wait
good luck with yours, i'll keep following it
