I've got a full size cab....big ol 4 player CP on the thing....its pretty, I love it...but its a monster.
Its also horizontal, with a 20" CRT acting as my monitor (for that s-video low-rez authentic look)

However....I have spares of everything but an optipac.... and I'm very much tempted to do a vertical dedicated cab.
Thing is...I have no more room, so I've been thinking of a Cabaret-style cab or even a vertical dedicated cocktail.......a bartop would likely be more practical, but it makes for some cramped 2 player action (I'm thinking vertical spinner joystick games like Time warriors, etc....and I dont havea bar. so then a MiniMame came into idea. A cocktail would be nice, but honestly cocktails are a pain in the butt to play after a little while, and I've already got all the end-tables I need in my home

I HALF thought about just adding a CP to the SIDE of my mame cab to make a franken-cab.....mount the monitor and tuck a control panel off the side.....I know, FUGLY but...you know...
I've got the space

(I dont run sideart on my cab due to the paint finish i chose).....
But I'm sure other folks have gone through this dilemma before......maybe a bartop...on a stand..to make it like a cabaret....I dunno.
Just curious what others have done.
