These white cases are actually from Imagin's HotRod Dental camera. When Atari went under, Imagin bought the Jaguar molds and modified them for their new dental camera. The camera has long been discontinued and someone from Imagin is selling off the remaining molds.
The obvious difference is the missing back and 2 moved posts on the bottom of the case (that the motherboard mounts too). There are some other minor differences as well.
In short, this case is not painted, it's white plastic. And technically, it's a dental camera shell modified to fit the Jaguar, which was modified from the Jaguar to fit the dental camera
On a standard Jaguar case, there is a back piece that hides the internals.
