Keyvan,

What do you think the smallest overall depth could be if I made a new case
for them???  I've already chopped out for the Fujis and have just under
50mm.  I don't want to chop out much more depth as the wall is engineering
brick - it's *very* tough.  If the depth of the touchscreen/PC is much more
then I could semi-recess it and put a frame around.

What's your best guess at a 'thin' mod????

Thanks

Simon

Thanks Dave

I did not know it was so complex...
I don't really see the need to disconnect the LCD, it has very easy
flush-mount side-brackets and even if one is short on mounting depth
then with some creative metalwork the depth could be at least halved
without seperating the lcd from mobo.
As it comes, the quality and brightness is evey bit as good as the
15" DVI Gateway lcd which I have had for a few years now.
