Good to see you used cutouts to check for carboy/keg capacity. I wish I had done that for my first kegerator.
The problem with covering the freezer is with how modern freezers are constructed. Old ones were designed with the condenser coils on the back so there could be good air flow around them. Now they put the coils under the skin of the freezer so that the outer skin of the freezer works to radiate heat from the coils. If you, in effect, insulate that skin from the ambient air, the coils do not cool properly, causing the compressor to work harder and shortening the life of the compressor.
If your girlfriend (kudos to her for letting you go to 10 gallons) doesn't like the appliance look, pick up a nice fabric covered folding Japanese screen to set in front of it. This will make a nice decorating touch for the room and will be easy to move to get access to the freezer.
