This just does not do it for me, sorry.
When I see a mame rig with a VGA monitor and an XArcade stick, all I can think is "wow, dude wants almost $1000.00 for a PC in a wood box"
Put a good old arcade CRT in that thing and output 15Khz, then match some native resolutions with AdvanceMame and i'd be more inclined to see it as something above garbage.
