I have three cabs in my garage, a countertop Neo Geo knockoff in my bedroom (:D), and a supergun.

Everything was pretty cheap, but they definitely take some on-going maintenance and take up a lot of space... not just space for the cabs but I've ended up with dozens of arcade PCBs over the last few years. There are so many great games that either never had home versions or had sub-par home ports. Also MAME is never 100% accurate and, to me, if you're going to make the effort to play in a real cab you should be playing an original PCB instead of semi-accurate emulation.

My cabs are:
- 25" Capcom Dynamo... currently marqueed as X-Men vs SF. It's horizontal JAMMA with a 2P, 6 button control panel so I can use it with most horizontal PCBs.
- 19" Guerrilla War... wired for vertical JAMMA with either a 2P rotary stick control panel or a standard stick 2P 2 button control panel. I can swap the control panel in about 10 minutes.
- 13" Neo Geo countertop... Mostly for the kids and currently running a 20-in-1 multi-Taito PCB. (Bubble Bobble!)
- Millipede... non-working. Gradually buying/replacing parts as I can afford it.

Some collectors like having dedicated original cabs for arcade classics but I'm happy sticking a JAMMA converter on my non-JAMMA PCBs. I'd rather have versatile cabs that cover each genre.

Eventually I'd like to add a light gun cab, 25" vertical JAMMA cab (keep Guerrilla War as a dedicated rotary), hi-res cab for my Naomi/Atomiswave, and a 2P linked sit-down racer. Then my garcade would be complete... until I find some cheap pinball machines.

I am soo jealous fella. If you fancy putting up some pictures some day feel free.

If my garage ever gets a clear out I guess thats the most logical place for one to go.

I has this:

Only gets used so often.  The trackball makes my arm flare up if used too much.

Eventually, if I can stop buying random things long enough to save up more, I'll probably buy.... er.... something else.  One of them big compilation ones fulla random retro titles.

Sure as heck have enough space in the basement for the damn things.
