This custom console by Arcade Controls forum member griffindod provides a barrel of fun. He made it in the hope of turning his hobby into a profitable enterprise:
Every time friends or family see my builds they always say the same thing "Oh you should make these and sell them", to which my answer is always the same "It's just not worth the man hours for what I could charge". With that being said there are people quite successfully making bar tops and selling them on a regular basis, and, I assume, turning a profit of some kind.
So, I thought I'd have a go at a 'Build-to-sell' project, trying to maximize the value of the finished product while keeping a very tight record of all of my costs and time to see how practical it is to build for profit. The goal is to build something fun and desirable to a decent standard, while keeping costs and man-hours to a minimum.
