After a couple of day's preparation the cabinet appeared on a Friday. A few days went by with no apparent work done (a hole remaining). They came back and filled in the hole and powered it up on the following Thursday. So it was just under a week but included several days with no activity (although they were installing a number of other cabs during that time).

Roughly how big are those things?

750x400x1228mm according to the planning applications that have had to go in for one or two. That seems about right.
