Review on SilverStone Tek ES02-PCIE – Wireless Power Remote with 2.4G Connection, Power/Reset Function, and Audio Feedback by Tom Goodlow

Great little multimedia PC add-on that turns on and restarts as naturally as the front panel buttons. Of course, some PC building experience is required to get it working - even though it's a PCI card, it still plugs in and depends on the motherboard's connectors. If you bought a pre-built PC, it may take some research to find where these headers are and hope the builder didn't come up with a custom, bespoke setup. IR version and also allows volume control of the start signal.
