ATX to bench power supply

I have need for a 5 volt supply and have a few “dead” ATX supplies kicking around. In looking for breakout boards to make things easy in the future, I noticed something very sad:

You can buy a kit of parts and solder everything in place for $22usd SparkFun Benchtop Power Board Kit - KIT-12867 - SparkFun Electronics

Or you can buy a completed board from various offshore places for under $10usd

I’d still probably buy the Sparkfun one, those people have been good to me for a few years.
