mining rig rack power upgrade

I recently got in enough parts to build 2 small 3x 7870 rigs (actually one card is a 7950). I needed at least 1 more power outlet because my first rig (5x 7970) was pulling 1200W on a nearby outlet, but I wanted to get a dedicated one for the first rig also.

My "rig rack" (built from the corner posts of an old server cabinet) had room for quite a few more motherboards so I decide to do a full bore power upgrade for future mining rigs.
