    Well, the main component of it is probably the microcontroller.

    I've talked to Jeff about making a two-stage timer that sends an ATX power-button momentary pulse after the first timer and cuts off power after the second.

    He thought it was something he could do, but I think he's real busy with those power supplies at the moment. :P

    Hmm, you could also do something based on my circuit:

    Just cascade two of them (i.e. power output of the first circuit goes to Vacc of the second. The second circuit won't need a diode or a power-off button.) to get a two-stage timer. The only tricky part is actually generating the momentary pulse when the first timer fires. Let me think about it for a bit...
