This is my new baby!

Just in case the picture did not load, the cab I am refering to is The King of Dragons (Capcom) cab, with small control panel.
I would like to change the CP for something larger. If I bought a CP, could it be mounted with minimal cutting.
I also want to use 4/8 way joys that a 5 year old can use.
Would it be hard to use the existing mount for a 21" PC minitor. The original monitor was 25"
Any advise from the cab gurus would be greatly appreciated. Thanks.
