I took a walk around the Castle Museum to get measurements for display cases and columns, as I struggled to imagine the size without any physical sense of it. Anna Green at the museum gave me a brief tour and also suggested that there might be an option of renting one (although I would have to drill holes for cables and vent... so this is unlikely to happen).
So, the height is to be around 1120-1150mm, length and width is to fit the glass fish tank in the NUCA basement.
