I finally got around to finishing my ATX breakout free build. After a long wait from parts from ebay and a long wait on the back of my work bench I finally finished it.
It wouldn't be a free build if something wasn't bodged together. In my case it was the ATX connector.
I got all the parts from ebay -- I couldn't find a right angle ATX connector on ebay, so I got a vertical one. I thought it would fit, but it didn't. So I ended up making it a right angle by bending the bottom row of pins and extending the top row of pins with 18ga finishing nails! It actually worked better than I expected. Also the push button I got from ebay was smaller than the footprint, but I was able to make it fit. The downside of buying from ebay.
You will also notice that the -12v LED is kinda cock-eyed. That's because I had to take it off and flip it around, I didn't really think about the fact that it was -12v when I plopped it down, so it was backwards. A trap for young players as Dave Jones would say.
Thanks so much DP, it's a great little tool and building free PCBs is so much fun!
Now that I have this, and all these power connectors sitting there. I am thinking about building a sister board which is a programmable supply using one of the other connectors. Maybe I'll start a design here.

You'll also notice that my PSU was the 24 pin variety, but it seems to work fine. Will the connector on the real product work in the same way with 24 pins (Because it has posts through the PCB). I wonder if it wouldn't be better if it came with a 24 pin connector (the top 20 pins are the same)

Nice build and writeup, thanks for sharing!
