My box measures 13.25 (H) x 6.75 (W) x 3.5 (D). The USB port protrudes the most at +.3125 above the face making total depth 3.8125". As far as cable stick out, the cable bundles are flexible and can be laid over within 1-2". But, the USB-B side of the included USB cable is rigid and will stick out 1.75" from the box face (includes the USB port).
Hope that helps.
