Also it look freaking massive..... there comes a point when you're paying nearly $500 for a huge power brick that you have to ask yourself - what is the point?
It's a fine looking bit of engineering, but I also have to question the cost and potential size.
OK, you're potentially making your case small without an internal 'traditional' PSU (ATX/SFX/TFX/Flex) but have to cart round a monster like this too, if you're on the move.
