The only one that looks right is the http://www.antec-inc.com/product/powers/pp250v.html
It says: PP250V is a 250 Watt 4-output, fan-cooled Baby AT Size (PS/2 Size) power supply designed for personal computer or industrial applications. It offers thermal controlled variable speed fan feature
(Smart Fan) for better cooling and quieter operation that assure long product life. It delivers the highest reliability and performance.
It doesn't say that it has the front switch module but I'm assuming that since you pointed me in this direction that it probably does?
