Doepfer Dark Time dimensions

Hi folks,
I am getting a Doepfer Dark Time sequencer for Christmas this year but won't be allowed to see or touch it until Christmas day - which is fair enough to be honest!!
However, I am going to convert the unit into a 'rack mounted' sequencer and I want to make a start on the fabrication of the box for it in advance and to do that, I need accurate measurements for the metal box (excluding the wooden sides). Doepfer do give this measurement in their specification data but they preface the measurements with the dreaded word 'about'.
I would be very much obliged if any existing owner would be kind enough to take a set of accurate metric measurements for me of the depth, width and height of the metal box portion.
Many thanks in advance.
