Let me start by saying I am VERY excited to be doing this. I saw MAME many, many years ago and I am pretty sure I installed it way back when and played some old arcade games with my my keyboard. At the time, I thought it would be awesome to build a cab as it was starting to become pretty common on the web. Alas, I was young, broke, and stupid and it never happened.
Fast forward to today, I am married and just had my first son. I told my wife last week, I think I want to build an arcade cab for video games and stick it in our garage (until we have a dedicated game room

)....her response...."okay"....I was shocked. So here I am....obsessively lurking and reading everything I can about cabinet building.
Onto the questions....
As to the design, I am fairly certain I am going to base mine off someone else's base design and tweak it a bit. I am decent when it comes to building things and I like more curves than blocky, but that's for another time.
I determined that I am going to use a 27" TV. Although an arcade monitor would be ideal, I plan on still accessing the computer side of the MAME box occasionally for updating, music, etc. and I understand arcade monitors are not the most "computer user-friendly."
1. First question, is it really that important to remove the TV from the housing and use just the tube? Or is it merely a space issue? Also, is there any place to go (easier than just googling) to find if the TV has the power restore function?
I have an old AMD Athlon 1800+ with 1.2 GB of RAM that I am going to use. It needs a new HDD as the one in there is old and slow, but that should be fine right? Before I start building, I am going to get the computer running with all the software, frontend, ROMS, etc. So I guess I'll know soon enough (just reformatted her last night).
My BIGGEST thing I have been wrestling with and what I need the most help on is the control panel.
I am a huge fighter fan (SF, MK, SNK, CAPCOM, etc.)...so I know that will likely be the BULK of my playing. That being said, I also love me some old games like Ghouls n' Goblins, TMNT, Tron, etc.....I am very much on the fence as to the configuration of my CP.
I really want to put four players on it for games like TMNT. I have friends and in-laws that I think would love the four-player. That immediately makes the CP large (I plan on doing a wrap-around type CP). So now I am at a larger CP. I don't know if I should add the spinner, ball, and analog sticks? I don't like the look of the franken panels, but in the same respect, I don't want to limit myself in playability.
So....how much am I limiting myself if I DON'T add in a analog 4-way stick and dedicated buttons for it. What games other than Tron use the spinner (I know there are a few, can't remember off-hand). Can I get away with a comp 8-way used for a 4-way game?
What would I be losing out on if I did only the typical fighter controls and MAYBE a spinner and ball.
Thanks, looking forward to many questions and posting my progress!
