Dimensions of enclosures

I've built a solid table to take a 840 machine (as yet unpurchased), and now see the enclosure is somewhat larger. The overall dimensions of the enclosure are given as 840: 1212 x 842 x 694 cm. What would be very very useful would be the dimensions of the rectangle of the enclosure foot centres, so that I can tell if I need to make the table larger to accommodate the enclosure, or if the current dimensions are sufficient.

May I suggest that these dimensions are quoted for all enclosures?
