Since the memory stick has to be constantly plugged in and out of the CubeX, it might not be a bad idea to plug a USB extender cable into the CubeX and then plug the memory stick into the extender cable. The extender cable is easily and cheaply replaced if it gets damaged from the frequent plugging in and out. - Just a thought.
Since the CubeX does not have a real power switch, it is advisable to plug the CubeX into a powerstrip with an on/off switch. That way if something goes wrong you can quickly turn it off, also easier for power off, than unplugging.
