Are you absolutely sure that there is no power switch? I thought there
was a small plastic button built into the back of the case, about 1/4"
diameter in the upper corner.
If there really isn't, there might be a connector on the motherboard for
soft-power on, or if you feel really devious, you can get a push button
switch, solder two wires onto it, and plug it into the right two holes in
the ADB port. Off the top of my head, there are five total connections on
ADB, the left two pins are DataTX and DataRX, the ground/sheild are the
outer metal part, and the right two pins are the equivalent of the power
key. Well if you short one of the two sets of pins it'll turn on, I just
don't remember which pair for sure.
