I'm currently in the process of rebuilding my MAME cab. I originally made it from an old PC and a free cabinet (bootleg MKII?) I got from a friend. I slapped an X-Arcade Tankstick on there and called it a day. After a couple of years, I sold it to my old boss for his kids.
About 2 months ago he called me and asked if I knew who would want to buy it. I told him I would give him what he paid me - $300. It was overpriced, but whatever. He's a good friend.
Anyway, this time around I'm going to be doing some upgrades and likely getting rid of the Tankstick (now that I know what I'm doing).
Started with uprading the rig to this:
ebay.com link: Dell Optiplex 7010 DT I7 3770 4GB RAM 500GB HDD Windows 10 Pro 4
What a deal! Had a spare SSD for a boot drive.
I also seriously plan on limiting the number of games this time around. I found that having thousands of games results in having no idea what to play and is overwhelming in terms of setup. Right now I have 159 games that I started configuring last night. The eventual plan is to upgrade to RGB LED buttons and have per-game button configs. That seems manageable with 200 games or less. I will add more games as I discover them along the way.
Here are a few *really* ancient pictures to give you an idea of the aesthetics.

Lots of work ahead of me on this bad boy.
