Some machine BIOSes have a Wake Up feature that you can enable. It automatically starts the machine at a given time. You can also enable the power saving mode of the monitor/system unit and add "Wake on Lan" capable NICs. If done correctly, PCs in sleep mode draw very little power.

There's also the possibility of X10 devices. I don't know if the price/savings will be worthwhile, but you can use them to shutdown machines that don't have the power saving features.
