Got a couple of my Single SCs last week, and found my first block ever! 714M difficulty! I also have a new AC unit being shipped to me, 10,000 BTU because these are running pretty hot (it was 95 degrees F out this day). Next up, running 2 new 20 amp breakers for room for expansion once all my other equipment gets here!

Whats that small black box connected to the ATX connector of the PSU? Just a switch or some kind of power distributor? Got a link?
It's a PSU tester to turn it on. If I ever need to turn it off I use the switch on the back of the PSU. Got it here: http://www.ebay.com/itm/370598121861?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649
