We are using HPRC 2760 cases. Ursa Broadcast rigged with HA22 lense and Fiber Converter fits exactly. furthermore there is space for the studio viewfinder and focus- & zoom remotes, as well as intercom headset and accessories.
The cases come with red padding (bottom and sides) and black dividers, which can be cut to size. We also used the dividers to cut out a screen protection for the viewfinders. In the lid there are pouches for small items.
To fix the black dividers that they stay in place we used some velcro paddings from B&W outdoor cases we had left over. This is the only caveat, since there is no solution out of the box from HPRC to keep the black dividers in place.
