[Cialug] OT - Looking for surplus power supplies

[David Champion]

The surplus PSU's are mostly hot-swap from HP servers. Some of the guys
have figured out how to use them.

We had talked about doing a how-to class on converting ATX PSU to a bench
power supply, we haven't done it yet but I think we might be able to stir
up support for that again.
