[SFDXA] Building Simple Bench Power Supplies from Your Old PC's

[Bill]

Convert your old PC Power Supply for use as a Power Supply for your Shop.

This guide has almost every ATX computer power supply to bench power 
supply published to date on Instructables ( as of Dec 2014, about 70 
unique instructables). It should be interesting to both those who want 
to do a conversion, and to those interested in the evolution of a 
popular topic that has been done over and over on the site. Sometimes 
the new projects had something to add sometimes not so much.
