Not to hate on the SimpleRigResetter, but I found this other product here that helps me:
http://www.ebay.com/itm/USB-PC-Watchdog-Computer-Reboot-Board-/132082381678I didn't want wires hanging from all the rigs to the SimpleRigResetter switch and wanted a more flush/compact way of the rig to automatically hard reset if anything happens to the computer (even BSOD and frozen computers).
To me, this seems more beneficial for my set up because it just plugs in the USB header and stays flush with the motherboard so there won't be anything dangling around. It is compatible with any motherboard that has a USB header. This should also help people who have their mining rigs at a remote location or data-center and can't have other wires dangling around across multiple rigs.
Advice: (Change your BIOS to always power on computer after a power-loss, and add this device, and add your mining program to automatically startup when computer boots, and it should help you maintain your rigs 24/7 uptime stress free).
Thought I share my finding. Hope this help others.
