Hi
I have mamed my existing arcade machine. I think its just a generic cab. Its the one in the pic:

I have changed the control panel to this:

however I want to change this to better make joysticks and buttons and install leds to run with mame. I also would like to add a trackball.
I currently have a 20-21" pc monitor in the cab at the moment which works fine but is now showing signs of wear so i may swap this out for my 22" lcd widescreen monitor( or i may buy a bigger lcd monitor). Because the lcd monitor is alot thinner im wondering if i can make the cabinet alot less shallower as i wont need the extra depth for the crt monitor.
Would it be a case of just cutting the back down like this (where i have marked):

I would just cut where i marked and then remount the back ,back on the cab. Would this work? (Im only suggest this as the wife has started to moan about the size of the thing!)
