Review on DKE Wireless Remote Control PC Power Switch RF External Computer Case Motherboard Button ATX Desktop On Off with USB 9-pin Power SW Cables by Darryl Blumenthal

Very good wireless power switch for computer. The cables have two female connectors that you can integrate with your existing case button (you can still turn the computer on from your case) or you can use it as a standalone power button. Another nice surprise was the ability to hard reset the PC by holding the button, just like a wired switch works. I have ordered two RFID devices that currently work with two separate PCs in the same office with no RF crosstalk. Assuming negative reviews are user error and not bad equipment, it's understandable that wiring can be tricky.
