hello all...been lurking here for a while, reading reading reading.....first post, just got approved

I've done allot of research, and found few systems I like the size/layout/aesthetics of...looking for min of 27" & 4 players. I've found some, thought I had it all sorted, and was getting ready to start a stand-up build, and ran into a dilemma....
I can acquire a Atari Gauntlet Dark Legacy system, within driving distance, near mint condition, fully working, for not much more then a similar shaped precut kit would cost for the cabinet alone.
1) is this a rare/limited/coveted machine?? Will I catch flak for gutting this to make an emulator system?
2) is it worth the work required to convert an existing cabinet, versus buying new?
3) I've been unable to find much on this system/cabinet/specs online....can anyone point me in the right direction?
thanks, looking forward to this build, and participating in this community
