I haven't read the thread, but the wall of text says that you guys are going at this waaaay too much...

hook them to the 5v rail and be done with it...

Well I'm trying to setup a switch that would differentiate from 5V to 12V, and Off.. and such.

It's a wall of text because I'm electrically stupid...

Found a cool article while surfin' da webz.

Pretty much talks about how to get 5V, 7V, or 12V through a switch, without using diodes..

Are there any cons to that version over Brians?
Thanks guys, and sorry for the excessive questions!

You can actually get 3.3v, 5v, 7v, 8.7, and 12v from a PC supply, but from experience, the 7v, 8.7v, and 12v are the usable voltages. The diodes are only needed if you want something different than those values.
