John, here's some good info to start:

note that commercial equipment has a separate compressor for the fridge and the freezer, not sure how that plays into cost/day as well as maintenance.
Given the 3 doors on the model you are looking at, you will either save a lot of e- or waste a lot. Putting all high traffic items into one of the three cubes should end up saving e- as you are warming up a smaller space on regular basis than one big space as in a typical residential style fridge. If you mix up things so you are constantly opening all the doors searching for something will certainly add to your e- bill. So it does require some planning.
it does look the part, I'll give you that. looking forward to any calc's you come up with.
