I am about ready to order one, but I also had a few questions. I also plan to connect it to my pi with jumper wire instead of mounting it directly. I read in the documentation that there is a slight voltage drop with in the power circuitry, so you need a good power supply. I was planning to use a 5V 6A power supply like this: http://www.jameco.com/webapp/wcs/stores/servlet/Product_10001_10001_323425_-1 Will using the ControlBlock to power the pi affect my ability to overclock? Will it affect my ability to power controllers/mouse/keyboard/thumb drive/wifi from the USB?
