MAMEWorld Forums - EmuChat - Can I make "GAUNTLET DARK LEGACY" into a MAME machine?

I would like to buy a sleek arcade machine locally using
craigslist and I need some advice. I want something with
a 25-27" arcade CRT and it needs to be ergonomic for
comfortable adult play.

From a bit of looking around, it would seem like these
games have a sleek look and are available for $500-$800 used:

Gauntlet Dark Legacy
NFL Blitz
The Simpsons

Basically I want to buy a machine and put a PC in it to play MAME.

So my 2 questions are:
1. Is there a favored arcade cabinet that most MAMErs use?
2. Will I run into video issues trying to connect a PC to
any of the 3 dedicated arcade cabinets I listed above?

Thanks for the help!
Tom
