Hi,
So I have decided I want to build a MAME box.  I was 11 years old in 1981 when my video game addiction began, and it was a full blown obsession until about 1984.  
One of the most important things I want to recreate with this MAME box is the physical sensation of being that size again.  I am currently 6'1".  But when I was playing video games, I remember that my head did not reach the bottom edge of the marquee.  So I am going to build my MAME box "oversized" so that the bottom edge of the marquee is an inch or so taller than I am right now.  The total height of the cabinet will be 8' or just under.  I don't want to have to use more than one piece of plywood for a side.  The room I am going to put this in has ceilings that are 8'3" high.  I figure I only need an inch or so of clearance (and yes, I know I will have to take the pegs/feet into account).  
My first question for the forum is:  how big of a monitor can I use?
Ideally, I'd like to find a Wells Gardner that can handle both CGA and VGA.  I am definitely going to mount it vertically.   I am looking for as an authentic look on the monitor as I can.  But as I also want the cabinet to be oversized, I can't use an original monitor.
I recently saw a 36" Wells Gardner for sale.  I wonder if this ends up having some problems because the images it projects are meant for a screen half that size.  Does the blockiness of the pixelation become a problem because the monitor is too big?  
I did a quick and dirty mockup of the cabinet using cardboard.  
I'm a little surprised to say that I kind of think this monitor was TOO big.  I wouldn't have thought that possible.  
I have Saint's book, and I see he used a horizontally mounted 27".  When I put that size into my mockup, that seemed okay.  I'm still tempted to go big, though.  So I thought I'd ask for opinions here.  
Thanks,
C.
