Nice looking system though my only comment would be for best part of £1200 quid I would not expect to lose 2 USB3 ports at the rear to power the front ones, would expect a motherboard with a header on for that.
It's happened Scan's 3XS system reviews on HEXUS in the past, as far as I can remember it gets overlooked, perhaps in relation to the partnership?
In fairness though, it's because the card reader uses the only USB 3 header, and motherboards with 2 USB 3 headers aren't that common. I'd probably sacrifice the decrease in speeds of a seldom used card reader and adapt down to a USB 2 header, I suppose this isn't the case for most Scan customers.
