Not sure why you'd need to unplug things though? My Tomahawk is all in the case, all power cables connected already, so all I'd need to do is plug a pendrive into one of the rear usb ports and press a button, that's all. Or do you mean you'd need to unplug things from your existing system?Similar position as you. My system now is all rigged up and CBA unplugging things just to flash the BIOS. Next week before putting the CPU in i'll flash it before
