What is the specification for the RB433UAH enclosure?

Just about to buy a RB433UAH to have a play with, but I’m lacking some information on the enclosure.

The pictures at http://www.routerboard.com/popup.php?kods=121&sess=c80383b2bf048efefd275cc7b221a233 seem to show it as a long case, but with cutouts for the USB sockets. The questions are therefore:

1 - Is the case shorter than the standard RB433 enclosure so the USB sockets stick out (in which case, how many of the mini PCI sockety things can be used?)

2 - Is it the same length as the standard RB433 enclosure (in which case, does it come with a USB extension cable?).
