I started a project two years ago to convert an empty TMTN cabinet into a MAME machine. I bought cab from a dude in Fort Worth for $50 because it could fit a big monitor.
I then installed a de-cased 27" Gateway presentation monitor into it using some crafty custom mounting. However, I just kind of dropped off with the project after that.
Fast forward two years... I've got this cabinet with bracing all in it, making it useless for anything other than the project I had started. The solution? Finish the project! It was always going to be a massive project, anyways. Now I'll finally get off my butt and finish it.
(Naturally, I still haven't finished the Space Invaders MAME project.)
