Greg Kennedy shows you how to make a DIY MAME cabinet project:
I started this project by taking stock of my components. Like any good hacker, I have a stack of spare PCs and monitors for occasions like this. I selected a set that was particularly hard to repurpose, due to its crappy CPU, use of expensive RDRAM, and then the monitor is a 13″ CRT. These specs would run a vertical cabinet with 4-way joystick nicely. The “modern” solution is to use some single board computer (say, Raspberry Pi) and an LCD. I’d rather not send e-waste off to the landfill, plus I’d have to pay for something I already have on hand!
