Great thanks for good feedback, and I really liked the video there @Shakz.
I actually got out and bought a better power supply and got rid of the yellow lightning bolt after I read your answers, however I couldn't find one that hosted a USB port rather than a fixed cable with a Micro USB-interface. I have now done a quick-and-dirty attachment of it to the PiNES but I'll try to find a better solution to be able to connect the power via a USB B cable since that will be better for transportation and general look overall.
However thanks again, I feel the subject is closed and I'll just have to find the proper gadget to handle it. :)
