Lacie manufacture uber flat USB extension cables.
Admire their flatness
lol, it's err... "pretty", but not quite what I had in mind

Black would be nice for starters! And that connector is mahooosive - would stick out of the front of the console and ruin the lines. A low profile right angled connector would be awesome. That way you can just fold the cable 180 degrees under the console (as its lying down) then round to the back.
Oh well, maybe Joytech or someone will make a stand with built in rear USB hubs?
Cheers,
