X men 6 player monitor box questions

[death69inc]

 I asked in another post but I thought I would make my own  hate hijacking

either case I have a 6 player x-men  missing monitor and box

need to remake the box so if anyone can help i need to clarify some items

picture from other post
box seems to have 2 wood stopper on each side and the l brackets on top and bottom
if i can get measurements on the bracket holes and stoppers it would be great

Monitor Box (houses the right side monitor which faces forward).
Height:  23"
Width:  26"
Depth:  20"

info from other posts  need to know for sure if these are outside dimensions and if it is 3/4" plywood or 1/2"

and last but not least if there are air vents on bottom of the box as there are in back wasn't sure if it has air inlets for the upper outlets etc

think that is it

If anyone can help it would be a great help!!!!
