Although I'm probably getting in way over my head, I've decided to build custom arcade cabinet running MAME. I've been playing around with MAME since 1997 or so. Just about every classic arcade game is available for it, provided you can find the ROMs. I've always wanted my own arcade cabinet, and building my own cabinet will allow me to customize it for the games I want to play.
I've created a separate weblog to chronicle the construction here. All updates for this specific project will be made on that site.
