I am currently working on a solution to this issue, though my board will require a Raspberry Pi to get the full functionality from it. PM me for details, I am currently waiting on the first batch of boards to finish testing before I post board files/code in this thread and elsewhere on the forum. I am considering selling kits on Tindie but want to gauge interest before I announce anything. Regardless of whether I do kit sales or not the required files for having your own copies produced will be posted, along with the full BOM and arduino code.

I plan on using these: http://www.karlssonrobotics.com/cart/atx-connector-breakout-board/?gclid=CKqhvv_Y7bcCFWrl7AodP00AHg
It's simple enough and gives you a way to mount it somewhere. You just need to put pins in two of the holes on it and you can probably find a nice switch/button that you can use to turn it on/off. You can find more complete versions of it with the power button on it already for a few bucks more. Just google "ATX Connector Breakout Board" and you will come up with a bunch of options.

I have read some of the comments on the sparkfun page for that item and it seems the circuit traces running from the ATX connector are not very wide. I would advise against trying to power the miners off this connection. Besides, according to the Klondike design you will power the miners from a standard 12V ATX connection, not the chunky 24 pin mobo connection. My solution introduces ACPI-shutdown like features to the RPi, delivering power and a way to gracefully shut off the RPi for maintenance, etc.
